-===========================================
-Define when an action plan is stale/invalid
-===========================================

-
-Problem description
-===================
-
-When an audit is created and launched successfully, it generates a new
-action plan with status **RECOMMENDED**. If the cluster data model has changed
-by and by, the action plan still remains in the **RECOMMENDED** state. There is
-not an expiry date or event that can invalidate the action plan so far.
-
-It should be possible to add a new **SUPERSEDED** state for action plan.
-
-Use Cases
-----------
-
-As a Watcher Administrator, I want watcher to update the state of any action
-plan from **RECOMMENDED** to **SUPERSEDED** automatically if the action plan
-has expired (default expiry time: 24 hours).
-
-As a Watcher Administrator, after the recommended action plan is launched
-successfully, I want watcher to update the state of any action plan based on
-the same cluster data model from **RECOMMENDED** to **SUPERSEDED**
-automatically.
-
-As a Watcher Administrator, when the cluster data model changes, I want watcher
-to update the state of action plan based on this cluster data model from
-**RECOMMENDED** to **SUPERSEDED** automatically.

-Proposed change
-===============
-
-* Add a new state **SUPERSEDED** for the **Action Plan**.
-* Add a new config parameter **action_plan_expiry**, This parameter is
-  used to set the time interval for checking the state of action plan.
-  Its type is Integer and the value is **24** (hours) by default.
-* Add a new **CheckActionplanState** class. In this class we use the
-  **APScheduler** library to check the state of action plan periodically.
-  **APScheduler** is a Python library that can schedule a job to be executed
-  later, either just once or periodically. It has been used in the continuous
-  audits, we just add our new job in the scheduler. The interval of the
-  periodic job is configurable.
-* Modify the **DefaultActionPlanHandler** class, trigger to check the state
-  of action plan.
-* Currently, when receives the specific event (such as nova notification
-  event_type:service.update, instance.update, instance.delete.end), the
-  decision engine will update the cluster data model. We need to add the state
-  of action plan updates to this process. To identify the action plan affected
-  by the cluster data model change, we distinguish by **audit.scope** field.
-  Only when the cluster data in the audit scope has changed, we update the
-  state of action plan. If audit.scope is null, we still update the state of
-  action plan when any cluster data is changed.
