package_tests: Invoke tests according to the specification

[stefwalter]

Lets invoke tests according to the specification in the following document section 1.7.2

https://fedoraproject.org/wiki/Changes/InvokingTests

The previous code took a lot of the interim state of the tests into account. Now that the tests are landing in dist-git lets do them in the perscribed way.

In particular:

• The tests launch the host and/or inventory that they need
• Provide a TEST_ARTIFACTS
• Invoke the playbook from within the dist-git repository
• Use the tests in dist-git proper
• Pass appropriate Ansible variables
• Use the inventory from the test if present
