With change Id34938c7bb8a5ca934d997e52cac3b365414c006
we require nova API version 2.56 or greater so we can
remove the compatibliity check in the
watcher_non_live_migrate_instance method.
The _check_nova_api_version method is left in place
for future compability checks.

This patch adds a scope to the datamodel, which only gets the VMs
of the specified nodes, and no longer gets all VMs from nova.

If hostname is different from uuid in Compute CDM,
get_compute_node_by_hostname method returns empty.
This patch set fixes to return a compute node even if hostname
is different from uuid.

If server migration fails, the while loop will not break
until retry to 0,
we can check the task_state to avoid this situation.

From nova api version 2.25(Mitaka release), the default value of
block_migration is None which is mapped to 'auto'.
So we can remove 'block_migration' from live_migrate_instance.

As of Nova API microversion 2.47, response of GET /servers/detail has flavor
which contains a subset of the actual flavor information used to create the
server instance, represented as a nested dictionary.
Since current watcher nova default api version is 2.53(Pike), This patch
follows the API response change.

This patch fixes the hardcoded value of availability zone
in nova-helper, Now nova api is used to get the availability zone
of destination node
Change-Id: I4c5a34946ed404df5bbfe34ce99873d32772dbf4
This patch removes the requirement to specify destination node,
for migrate action. There can be some strategies that wants to rely
on nova-scheduler for destination node. It will not impact any current
strategy behavior.

Getting images from Novaclient is refered as proxy API
and was deprecated to use in nova. We should use
Glanceclient to get images instead.

The function nova.servers.list() will return a huge context in the

In this changeset, I implemented the notification handling (Rx only)
system for consuming incoming notifications, more especially the Nova
ones. The notifications handlers also contain the logic which
incrementally updates the Compute model.

The nova helper does not have a sufficient code coverage.
This commit raises its coverage from 39% to 89%.
And unit tests find two bugs.

In this changeset, I refactored the whole Watcher codebase to
adopt a naming convention about the various elements of the
Compute model so that it reflects the same naming convention
adopted by Nova.

The OpenStackClients class provides a convenient way to create and
cache client instances. The idea behind this code comes from Magnum
[0].
The OpenStackClients class will act as the manager of other project's
clients, providing an easy way to fetch instances of said clients. This
will allow the clients to be cached.
An instance of OpenStackClients is created for every call that comes
into the decision engine and the applier, using the request context to
pass needed (domain id) parameters to get a Keystone session. This
instance should be shared as much as possible to avoid additional
unneccessary connections to the other services.
This class will also allow for the version of each client to be
configurable via the watcher.conf file.
The method by which a Keystone session is also changed to use the
keystoneauth1.loading library. In order to avoid DuplicateOptErrors
with the keystone_authtoken group used for the keystonemiddleware in the
API code, a new conf group named "watcher_clients_auth" is created. A
typical configuration using a password authentication scheme will look
like:
[watcher_clients_auth]
auth_type = password
auth_url = http://<server-ip>:<port>
username = <username>
password = <password>
project_domain_id = default
user_domain_id = default
