Proposal to move all stadium projects from neutronclient to openstackclient repo. Tap-as-a-service is the first example. The tapas osc client code was recently moved to neutronclient see https://review.opendev.org/c/openstack/tap-as-a-service/+/960849 but proposal is to make openstackclient its final destination. This change also includes automatic lint fixes required in this repo. Change-Id: Ied47f40c6947600d40bf675ec06f0bf88fd15f1f Signed-off-by: Miro Tomaska <mtomaska@redhat.com>
