ansible-playbook now works when run with a playbook
that includes a role that includes another role
specified using csv format
Updated one of the roles used in the tests to fix
broken tests - `make test_galaxy` now works
Fixes#11486. Also addresses the problem alluded to in #10620.
Older git archive commands create tar archives even with a tar.gz
extension. So change it to always create tar archives and have
the install_role method cope.
Removed ssh roles from the test case as they don't work unless
you can connect to bitbucket via ssh and have your key there.
Corrected a minor typo in error messages
* Roles can now be given a friendly name as third field in role spec csv
* Roles can be installed from URL (not just from archived SCMs)
* Integration tests to demonstrate this
* Unit tests to ensure that role spec parsing works as expected
