Description

It would be nice if we could track the Admission Control / queue information from the StateStore WebUI.

The topics page just shows a summary about "impala-request-queue" but nothing on the details of the queues / number of queries / mem usage.
Besides showing this on the WebUI, it would be nice to have it logged, so there would be some kind of historical view.

These would enable to track issues when a query is rejected due to admission control.
