Improve CI (#528)

* Update CI scripts to be more close to the ones in ansible-core.

* Extend CI matrix.

* Make sure that docker daemon is running (when not in a container).

* Make sure that connection plugin tests do not uninstall Docker daemon.

* Check some conditions.

* Fix error ignores.

* Skip SSH test on Alpine VMs.

* Take care of more errors.

* Adjust for more errors.

* Improve conditions.

* Remove new entries from CI matrix; make CI matrix nicer.
