    Attachment: YARN-6741.004.patch

Thanks [~sunilg], i have updated the test case, to capture the scenario which you mentioned,
where in one of the children queue is yet in RUNNING state and refresh gets called with all
children deleted.

> If we configure CS such that all  children of a parent queue are deleted and made as
a leaf queue, then {{refreshQueue}} operation fails when re-initializing the parent Queue
> {code}
>        // Sanity check
>       if (!(newlyParsedQueue instanceof ParentQueue) || !newlyParsedQueue
>           .getQueuePath().equals(getQueuePath())) {
>         throw new IOException(
>             "Trying to reinitialize " + getQueuePath() + " from "
>                 + newlyParsedQueue.getQueuePath());
>       }
> {code}
> *Expected Behavior:*
> Converting a Parent Queue to leafQueue on refreshQueue needs to be supported.
