* Install galaxy roles before running ansible tests
* Use package module in kolla-ceph to support Debian-based systems
This is required for running tests in TravisCI.
* Fix kolla-ceph unit test
* Add more tests for kolla-ceph
Journal tests are currently failing on my laptop due to partition labels
being truncated.
* Add .gitignore for stackhpc.parted-1-1 galaxy role
* Run all test cases
Run all test cases, collecting failures, then report at the end.
