* Fix bad sysctl command in README
* Add --suite and --test flags to integration tests
So we can run a single suite or a single test without having to edit
any code.
* Drop several skipped integration tests
Many of these skips are no longer necessary. Didn't do an exhaustive
check of all skipped tests, so this is just a start.
* Simplify cleanup make target
* Use more inclusive language
* Don't bail on failing tests without --bail
* Skip a few more free suite tests
* Default to https when running platinum tests
* Add make targets for local integration testing
* Linter cleanup
* Skip some platinum integration tests
* Improvements to integration test README
* Another free test to skip for now
* Continue on non-bail test failure
* Output cleanup
