Without this change the "Import variables specific to distribution"
tasks fail with "Could not find file on the Ansible Controller..."
on environments with inject facts disabled.
This changes the tests to run with ansible with
inject_facts_as_vars = false and fixes other roles and playbooks.
Most tests have simply been using the Tests as name, but this there is a
lack of information in automated runs. The name should be similar to the
test file name.
The changed flag returned by ipahostgroup calls have not always been correct.
The use of the module with IPA version 4.6 on RHEL-7 resulted in encoding
errors. All this has been fixed.
Addtitionally new test cases have been added to make sure that the issues
are solved.
