Description

Currently, if there is no pending ask or running container for an app, we transmit it to the "Waiting" state. To step further, we keep the "Waiting" state for a short period of time and then transit the state to "Completed".

Before YUNIKORN-2 is done, this is to track the core side changes to do the state transition. When the app moves to the completed state, the core needs to send a "UpdateResponse#UpdatedApplication" so the shim can do proper cleanup.
After YUNIKORN-2 is done, when the app is "Completed", core needs to ask the shim to release all the placeholder pods.
