The ingest docs in Elasticsearch doing point to the actual ingest APIs.
This makes up generate links to the real APIs instead, fixing some
broken links in the 5.x docs in the process.
Handles a few "special" doc urls from ES's api spec files. These are
only a problem in 6.x but we'd like to keep the generateDocs script the
same across all branches for easier backporting.
