The new client adheres to the standards of the other clients now. It prints out tables, uses ENVVAR's for auth, no longer stores pickled json in a login token, uses openstack common, and moves the cli operations into a v1 module for the future of trove when it has a v2 api. Please note for compatibility, the troveclient.compat module has the old cli. In order to deploy it, amend the setup.cfg to include the compat module. implements blueprint cli-compliance-upgrade Change-Id: Ie69d9dbc75ce90496da316244c97acca1877a327
