Seeing quite a few test failures on this, need to investigate and fix.

Seeing quite a few test failures on this, need to investigate and fix.

The root cause of error test cases is that we can't add child queue to a draining queue. In the first case, we add three queues root.fence, root.fence.child1, and root.fence.child2. After we reset the configuration, these three queues will get into the draining state. Then, another case tries to add child queues to root.fence and the case gets error.

Currently, the yunikorn-core will clean draining queues every 10 seconds. The duration is hardcoded in the source code. Users can't update it. Do we want to add the setting to the configuration? If yes, I can help to add it.

A better approach is probably to use distinct queue names for different tests so that they don't conflict.
