Add one or more playbooks to run tests using ansible on the target host

[tyll]

Currently, the tests use Ansible from the local host to run tests on the host specified in the inventory. The CI runner uses Fedora 32 for this. To test that the role also works with the Ansible/python libraries such as Jinja2 on the other distributions.

Possible solution:

• Copy role with tests to the target host (maybe standard-test-roles can help here)
• install Ansible there (maybe even from git with multiple versions)
• run the tests against localhost (this might need some fixes so that all tests can run after each other
• do this for certain distributions: Probably CentOS 7 and CentOS 8 and maybe Fedora
