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. https://blueprints.launchpad.net/watcher/+spec/notifications-actionplan-cancel Change-Id: I895a5eaca5239d5657702c8d1875b9ece21682dc Partially-Implements: blueprint cancel-action-plan
