This patch adds feature to cancel action plan in watcher.
A General flow from watcher-api to watcher-applier is implemented.
action plan cancel can cancel any [ongoing, pending, recommended]
action plan, it will update the action states also to "cancelled".
For ongoing actions in action plan, actions needs to be aborted.
Seperate patches will be added to support abort operation
in each action.
Notification part is addressed by a seperate blueprint.

Currently if user wants to skip some host_aggregates from audit,
it is not possible. This patch adds host_aggregates into the exclude
rule of audit scope. This patch also implements audit-tag-vm-metadata
using scopes.
TODOs:
1. Add tests
2. Remove old implementation of audit-tag-vm-metadata

New audit state SUSPENDED is added in this patch set. If audit
state with continuous mode is changed from ONGOING to SUSPENDED,
audit's job is removed and the audit is not executed.
If audit state changed from SUSPENDED to ONGOING in reverse,
audit is executed again periodically.

We have two controllers as HA in our OpenStack environment.
There are watcher-applier and watcher-decision-engine in each
controller. So there are two same name in the services table.
In this case, the objects.Service.get_by_name(context, name)
will trigger exception of MultipleResultsFound.
We should use objects.Service.get(context, id) replace of
objects.Service.get_by_name(context, name).

The 'strategy_id' attribute is the one that not exposes
to API. But the 'PATCH' API always update this attribute.
So this change does not work when choose 'remove' op.
This patch sets value for 'strategy_id' attribute.

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).

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.
