Add Watcher client support
32308a1 
Add get_watcher_session_client() helper function to build a
watcherclient.v1.Client instance authenticated with a keystone session
that uses admin credentials by default.

(cherry picked from commit 03875e1)

Use None as get_nova_session_client() version default
3d17c1e 
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.

launch_instance: expose nova api version and target host
e0cf425 
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.

resource_reaches_status: add new parameter stop_status
cfc0fb0 
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')

Log available attributes on AttributeError
b129d57 
This simplifies when developing new tests and the programmer is not too
familiar with the different attributes an object has.

(cherry picked from commit 42e9404)
@freyes @wolsen
Add watcher test.
8d600ff 
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.
