The function nova.servers.list() will return a huge context in the
large infrastructure. We can use nova.servers.get() instead of it.

Submitted state is not referenced nor used in the Watcher codebase,
and hence removed the references to the state from the codebase.

In this changeset, I added the "action_plan" ObjectField which can
either be loaded by setting the new "eager" parameter as True
or not loaded (as before) by setting it to False. The advantage of
introducing this eager parameter is that this way,
we can reduce to a minimum the overhead of DB queries whenever the
related object fields is not actually needed.

In this changeset, I modified all existing Watcher objects to now
rely on oslo.versionedobjects as a base.

As we are about to version the Watcher objects, we need to make sure
that upcoming model/object modifications are additive in order to
avoid having to bump the major version of the API. Therefore,
this changeset removes 4 unused DB fields that were exposed in their
associated Watcher objects (i.e. AuditTemplate and Audit).

In this changeset, I added ORM relationships to the DB models
concerning the already-declared foreign keys.
I also modified the DB query building to now handle a new 'eager'
parameter that, if True, is responsible to also fetch the data
relative to these 'parent' DB entities (no cascading).

This patch is deprecated use xx = [] for the parameter initial value,
this parameter will only be initialized at the first call,this is not
what we expected.
Better choice is to set the initial value to None,
then initialize xx with xx= xx or [] in method body.
