IMPALA-3102: Admission control supportability

A few small but important supportability improvements for
admission control:
1) Set the admission control resource pool before calling
   into scheduling.
2) Set the summary profile info strings for queuing
   information before blocking on the queue.
3) Some minor logging changes.

1 and 2 will expose important information before a request
is queued so that users can observe what is happening while
a query is waiting to be admitted.

This has been tested manually on the 6-node cluster.
