This allows callers to pass None and let get_nova_session_client() to use a sane default API, specifically this allows intermediate users (e.g. launch_guest() ) to proxy values passed by the caller. (cherry picked from commit 3283ed4) (cherry picked from commit dd72af4) (cherry picked from commit 3d17c1e)
This change exposes two new parameters in the launch_instance() function: - nova_api_version: Set the microversion the novaclient should use. - host: Request to launch the instance on a specific hypervisor host. (cherry picked from commit be6ba2a) (cherry picked from commit 41d4e42) (cherry picked from commit e0cf425)
The stop_status parameter allows callers to ask stop retrying based on a
list of statuses that are known to be final (and error) states, this
saves time failing earlier.
Usage example for fail early when an instance reaches to ERROR status:
openstack_utils.resource_reaches_status(self.nova_client.servers,
instance_uuid,
resource_attribute='state',
expected_status='ACTIVE',
stop_status='ERROR')
(cherry picked from commit 11c3f80)

(cherry picked from commit cfc0fb0)
This test launches 1 instance per hypervisor, and then launches a new audit to optimize the use of hypervisors and consolidate the instances in a single hypervisor, but also disabling the nova-compute service to avoid new instances get allocated. (cherry picked from commit 6787c84) (cherry picked from commit 35741f1) (cherry picked from commit 8d600ff)
