Description

With YARN-9879, the Capacity Scheduler now use full queue path instead of leaf queue's name, we should also reflect this change in scheduler UI page.

This issue addresses two changes:

1. Fixed and refined queue filter logic: instead of exact matching of leaf queue's name, now use prefix matching for non-leaf queue, and exact matching of full queue path for leaf queue.
   This change conforms to the logic of FS.
2. Fixed openQueues parameter change behavior in URL during queue expansion and collapsing, by not displaying the "Queue: " prefix with each leaf and non-leaf queue.
   Prior to this change, queue collapsing does not remove the corresponding queue name from the openQueues parameter, due to the "Queue: " prefix contains a space, which is encoded as '%20' and therefore not matched cleanly.
   This change also conforms to the logic of FS.
