Bumped v6.7.0-rc.2

Node.js v6 will go EOL at the end of April 2019, and already two of the production dependencies of the client have already dropped support for it, and soon others will do *(as well as development dependencies)*.

Furthermore, since Node.js will go in EOL it will never get security patches, plus, also OpenSSL-1.0.2 will go EOL [this year](https://github.com/nodejs/Release#release-schedule); to avoid risks for the client users it is better to drop support for Node.js v6 right away.

 - TypeScript support out of the box.
 
 ## Install
@@ -26,98 +25,40 @@ The official Node.js client for Elasticsearch.
 npm install @elastic/elasticsearch
 ```
 
-### Node.js support
-
-NOTE: The minimum supported version of Node.js is `v8`.
-
-The client versioning follows the Elastc Stack versioning, this means that
-major, minor, and patch releases are done following a precise schedule that
-often does not coincide with the [Node.js release](https://nodejs.org/en/about/releases/) times.
-
-To avoid support insecure and unsupported versions of Node.js, the
-client **will drop the support of EOL versions of Node.js between minor releases**.
-Typically, as soon as a Node.js version goes into EOL, the client will continue
-to support that version for at least another minor release. If you are using the client
-with a version of Node.js that will be unsupported soon, you will see a warning
-in your logs (the client will start logging the warning with two minors in advance).
-
-Unless you are **always** using a supported version of Node.js, 
-we recommend defining the client dependency in your
-`package.json` with the `~` instead of `^`. In this way, you will lock the
-dependency on the minor release and not the major. (for example, `~7.10.0` instead
-of `^7.10.0`).
-
-| Node.js Version | Node.js EOL date | End of support         |
-| --------------- |------------------| ---------------------- |
-| `8.x`           | `December 2019`  | `7.11` (early 2021)    |       
-| `10.x`          | `Apri 2021`      | `7.12` (mid 2021)      |        
-
 ### Compatibility
 
-The library is compatible with all Elasticsearch versions since 5.x, and you should use the same major version of the Elasticsearch instance that you are using.
+The minimum supported version of Node.js is `v8`.
 
-| Elasticsearch Version | Client Version |
-| --------------------- |----------------|
-| `master`              | `master`       |
-| `7.x`                 | `7.x`          |
-| `6.x`                 | `6.x`          |
-| `5.x`                 | `5.x`          |
-
-To install a specific major of the client, run the following command:
+The library is compatible with all Elasticsearch versions since 5.x, but you should use the same major version of the Elasticsearch instance that you are using.
 ```
-npm install @elastic/elasticsearch@<major>
+# Elasticsearch 7.x
+@elastic/elasticsearch@7
+
+# Elasticsearch 6.x
+@elastic/elasticsearch@6
+
+# Elasticsearch 5.x
+@elastic/elasticsearch@5
 ```
 
-#### Browser
+## Usage
 
-WARNING: There is no official support for the browser environment. It exposes your Elasticsearch instance to everyone, which could lead to security issues.
-We recommend that you write a lightweight proxy that uses this client instead, you can see a proxy example [here](./docs/examples/proxy).
+You can find the full documentation in our [docs](https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/index.html) website.

-## Quick start
-
-First of all, require the client and initialize it:
 ```js
 const { Client } = require('@elastic/elasticsearch')
 const client = new Client({ node: 'http://localhost:9200' })
-```
 
-You can use both the callback-style API and the promise-style API, both behave the same way.
-```js
 // promise API
 const result = await client.search({
   index: 'my-index',
-  body: {
-    query: {
-      match: { hello: 'world' }
-    }
-  }
+  body: { foo: 'bar' }
 })
 
 // callback API
 client.search({
   index: 'my-index',
-  body: {
-    query: {
-      match: { hello: 'world' }
-    }
-  }
+  body: { foo: 'bar' }
 }, (err, result) => {
   if (err) console.log(err)
 })

+### Client options
 
-Let's see a complete example!
-```js
-'use strict'
+The client is designed to be easily configured as you see fit for your needs, following you can see all the possible options that you can use to configure it.
 
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({ node: 'http://localhost:9200' })
-
-async function run () {
-  // Let's start by indexing some data
-  await client.index({
-    index: 'game-of-thrones',
-    // type: '_doc', // uncomment this line if you are using Elasticsearch ≤ 6
-    body: {
-      character: 'Ned Stark',
-      quote: 'Winter is coming.'
-    }
-  })
-
-  await client.index({
-    index: 'game-of-thrones',
-    // type: '_doc', // uncomment this line if you are using Elasticsearch ≤ 6
-    body: {
-      character: 'Daenerys Targaryen',
-      quote: 'I am the blood of the dragon.'
-    }
-  })
-
-  await client.index({
-    index: 'game-of-thrones',
-    // type: '_doc', // uncomment this line if you are using Elasticsearch ≤ 6
-    body: {
-      character: 'Tyrion Lannister',
-      quote: 'A mind needs books like a sword needs a whetstone.'
-    }
-  })
-
-  // here we are forcing an index refresh, otherwise we will not
-  // get any result in the consequent search
-  await client.indices.refresh({ index: 'game-of-thrones' })
-
-  // Let's search!
-  const { body } = await client.search({
-    index: 'game-of-thrones',
-    // type: '_doc', // uncomment this line if you are using Elasticsearch ≤ 6
-    body: {
-      query: {
-        match: { quote: 'winter' }
-      }
-    }
-  })
-
-  console.log(body.hits.hits)
-}
-
-run().catch(console.log)
-```
-
-## Install multiple versions
-If you are using multiple versions of Elasticsearch, you need to use multiple versions of the client. In the past, install multiple versions of the same package was not possible, but with `npm v6.9`, you can do that via aliasing.
-
-The command you must run to install different version of the client is:
-```sh
-npm install <alias>@npm:@elastic/elasticsearch@<version>
-```
-So for example if you need to install `7.x` and `6.x`, you will run
-```sh
-npm install es6@npm:@elastic/elasticsearch@6
-npm install es7@npm:@elastic/elasticsearch@7
-```
-And your `package.json` will look like the following:
-```json
-"dependencies": {
-  "es6": "npm:@elastic/elasticsearch@^6.7.0",
-  "es7": "npm:@elastic/elasticsearch@^7.0.0"
+```ts
+{
+  // the Elasticsearch endpoint to use
+  node: string | string[];
+  // alias of above
+  nodes: string | string[];
+  // custom connection class
+  Connection: typeof Connection;
+  // custom connection pool class
+  ConnectionPool: typeof ConnectionPool;
+  // custom transport class
+  Transport: typeof Transport;
+  // custom serializer class
+  Serializer: typeof Serializer;
+  // max number of retries for each request
+  maxRetries: number;
+  // max request timeout for each request
+  requestTimeout: number;
+  // max ping timeout for each request
+  pingTimeout: number;
+  // perform a sniff operation every `n` milliseconds
+  sniffInterval: number;
+  // perform a sniff once the client is started
+  sniffOnStart: boolean;
+  // custom sniff endpoint, defaults `_nodes/_all/http`
+  sniffEndpoint: string;
+  // perform a sniff on connection fault
+  sniffOnConnectionFault: boolean;
+  // configurethe node resurrection strategy, default `ping`
+  resurrectStrategy: 'ping' | 'optimistic' | 'none';
+  // adds `accept-encoding` header to every request
+  suggestCompression: boolean;
+  // enable gzip request body compression
+  compression: 'gzip';
+  // ssl configuraton
+  ssl: http.SecureContextOptions;
+  // http agent options
+  agent: http.AgentOptions;
+  // filters which node not to use for a request
+  nodeFilter: nodeFilterFn;
+  // custom selection strategy, defaults `round-robin`
+  nodeSelector: nodeSelectorFn | string;
 }
 ```
-You will require the packages from your code by using the alias you have defined.
+
+### Request specific options
+If needed you can pass request specific options in a second object:
 ```js
-const { Client: Client6 } = require('es6')
-const { Client: Client7 } = require('es7')
-
-const client6 = new Client6({ node: 'http://localhost:9200' })
-const client7 = new Client7({ node: 'http://localhost:9201' })
-
-client6.info(console.log)
-client7.info(console.log)
+// promise API
+const result = await client.search({
+  index: 'my-index',
+  body: { foo: 'bar' }
+}, {
+  ignore: [404],
+  maxRetries: 3
+})
 ```
-
-Finally, if you want to install the client for the next version of Elasticsearch *(the one that lives in Elasticsearch’s master branch)*, you can use the following command:
-```sh
-npm install esmaster@github:elastic/elasticsearch-js
+The supported *request specific options* are:
+```ts
+{
+  ignore: [number], // default `null`
+  requestTimeout: number, // client default
+  maxRetries: number, // default `5`
+  asStream: boolean, // default `false`
+  compression: string, // default `false`
+  headers: object, // default `null`
+  querystring: object // default `null`
+}
 ```

+   * @param {string} df - The field to use as default where no field prefix is given in the query string
+   * @param {number} from - Starting offset (default: 0)
+   * @param {boolean} ignore_unavailable - Whether specified concrete indices should be ignored when unavailable (missing or closed)
+   * @param {boolean} allow_no_indices - Whether to ignore if a wildcard indices expression resolves into no concrete indices. (This includes `_all` string or when no indices have been specified)
+   * @param {enum} conflicts - What to do when the delete by query hits version conflicts?
+   * @param {enum} expand_wildcards - Whether to expand wildcard expression to concrete indices that are open, closed or both.
+   * @param {boolean} lenient - Specify whether format-based query failures (such as providing text to a numeric field) should be ignored

+   * @param {list} _source_includes - A list of fields to extract and return from the _source field
+   * @param {number} terminate_after - The maximum number of documents to collect for each shard, upon reaching which the query execution will terminate early.
+   * @param {list} stats - Specific 'tag' of the request for logging and statistical purposes
+   * @param {boolean} version - Specify whether to return document version as part of a hit
+   * @param {boolean} request_cache - Specify if request cache should be used for this request or not, defaults to index level setting
+   * @param {boolean} refresh - Should the effected indexes be refreshed?
+   * @param {time} timeout - Time each individual bulk request should wait for shards that are unavailable.
+   * @param {string} wait_for_active_shards - Sets the number of shard copies that must be active before proceeding with the delete by query operation. Defaults to 1, meaning the primary shard only. Set to `all` for all shard copies, otherwise set to any non-negative value less than or equal to the total number of copies for the shard (number of replicas + 1)
+   * @param {number} scroll_size - Size on the scroll request powering the delete by query
+   * @param {boolean} wait_for_completion - Should the request should block until the delete by query is complete.
+   * @param {number} requests_per_second - The throttle for this request in sub-requests per second. -1 means no throttle.
