Introduce client testing

This is a first implementation probably a bit raw.
So it needs improvement.

Tests require:
- docker available on host.
- docker credentials to the user who is running the tests.

Current tests:
- Check docker socket
- Check docker can be used by api.
- Check source installation on Ubuntu, Debian, Fedora.
- Check pip installation in Fedora.
- Check if client can show an empty configuration.
- Check client version format (basic).
