* 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.
Previously, the external network carried both public API traffic and
neutron external network traffic. In some cases is it useful to separate
these networks. The public network now carries the public API traffic,
leaving the external network to carry neutron external network traffic
alone. For backwards compatibility, the public network defaults to the
external network.
