Description of problem: While testing the feature of changing the type of an existing volume, the default Cinder CLI options (using help) didn't show the new command "cinder retype". The command is available, though, on Cinder's API v.2, with the addition of the flag "--os-volume-api-version". The two available Cinder API versions should be available to the user as a default. The user doesn't know, and should not be bothered with the version of the API that he uses. Version-Release number of selected component (if applicable): openstack-cinder-2014.1-3.1.el7ost.noarch python-cinder-2014.1-3.1.el7ost.noarch python-cinderclient-1.0.8-1.el7ost.noarch How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
v2 options are shown if env var OS_VOLUME_API_VERSION=2 is set.
