With the recent changes to devstack and the migration
of the trove utility 'redstack' to 'trovestack' a number
of unnecessary items were brought over. This change
attempts to fix some problems and clean up some issues:
- Environment variables are ignored.
- Credentials are taken from the clouds.yaml file or
sourced from the devstack/accrc/{project}/{user} directory.
This means that authentication is now done through the
mechanism specified by devstack.
This should fix the kick-start and clean issues.
- The openstack client is used wherever possible with the
same set of credentials as mentioned above.
- References to stable/<branch> have been removed.
- The trove devstack plugin is assumed to be in the trove repo.
- Sourcing /tmp/integration/env.rc has been removed (items in
this file can be moved to ~/.trovestack.options.rc if needed).
- set_home_dir was removed.
- The fault flavors no longer set up 'resize' versions of themselves.
- Help for int-tests was improved to add scenario examples and
a few other minor clarifications.
This should fix the issues people may have been having with
'kick-start' giving an authentication error after sourcing the
openrc file or 'clean' not running properly. There should be
no more 'plugin already enabled' style errors either.
Note: The original code for switching to V3 of authentication was
removed as it wasn't an issue with kick-start/clean up per se.
It still should be fixed, but as a separate set of changes.
