Add a new config option 'action_execution_rule' which is a dict type.
Its key field is strategy name and the value is 'ALWAYS' or 'ANY'.
'ALWAYS' means the callback function returns True as usual.
'ANY' means the return depends on the result of previous action
execution. The callback returns True if previous action gets failed,
and the engine continues to run the next action. If previous action
executes success, the callback returns False then the next action
will be ignored.
For strategies that aren't in 'action_execution_rule', the callback
always returns True.
If exception is throwing out during the action execution, reverting will
be triggered by taskflow. To continue executing the next action,
we return False instead of throwing an exception.

It will firstly migrate all instances from the maintenance node
to one backup node. If not, it will migrate all instances,
relying on nova-schduler.

By the input parameter "metrics", it makes decision to migrate a VM
base on cpu or memory utilization.
Change-Id: I35cce3495c8dacad64ea6c6ee71082a85e9e0a83
Metric 'memory.usage' depends on balloon driver,
and shows the memory usage inside guest-os,
while 'memory.resident' represents volume of RAM
used by the instance on the physical machine
So, it is more reasonable to use 'memory.resident'
when calculating node utilization
by gathering instances utilization of the node.

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.

New audit state SUSPENDED is added in this patch set. If audit

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.
