* Add more tests.
* Added tests for CA options.
* Don't run in docker-in-docker situations where docker daemon becoming instable is really dangerous. Also, restart docker daemon after tests.
* Only run CA tests when openssl_certificate can be run (which is not the case for RHEL7, see #34054).
* Add comment on why docker-based CI runs are skipped.
* Update Shippable integration test groups.
* Update integration test group aliases.
* Rebalance AWS and Azure tests with extra group.
