Fix ansible-lint linter definition. (#3601)

* Fix ansible-lint linter definition.

Use ansible-lint's feature auto-detection instead of temporary file.
For auto-detection to work, ansible project has to be also a git repository.

Don't use yaml rules. These are checked by yamllint.

Refactor pattern to work with ansible-lint >=5.0 version.

Clean-up obsolete test cases.
