Description

Ambari server has recently had added the ability to cancel operations (AMBARI-1897) but is not able to cancel operations that are timing out in yellow and gets stuck in this state for several minutes, blocking restarts of other components.

I've attached a screenshot which shows there is no X next to the operations in yellow that are stalled.

This is the result of a hang on an ambari client (scenario documented in AMBARI-8768) but highlights that Ambari server's ability to cancel operations needs hardening and the ability to cancel any operation in any state to recover the operations queue.
