I could think of a (possible) future use case that we want to be able to
deactivate an application (e.g. maintenance mode) without undeploying it,
wdyt ? What are the application states we are currently supporting ?
At that point we can add another status InMaintainace which is handled
differently. Created, activated, inactive, terminating and terminated are
the available states currently.

Application, Group and Cluster Monitors' statuses to 'Terminating' and
start terminating members. The monitors will get removed. Also, the
relevant events will be sent via the Application Status topic and CC will
update the Topology with the correct statuses for Clusters, Groups, etc.

It should be. I get the feeling Isuru also has meant the same.
