IMPALA-1575: Yield admission control resources at query end

Currently, a query does not release admission control
resources until the client calls UnregisterQuery. Slow
clients can hold admission control resources even after
the query is finished. Specifically, in the following
cases, the query is completed, but the client must
still call UnregisterQuery to release admission control
resources:

1. The query encounters and error and fails
2. The query is ended due to the idle query timeout
3. The query reaches eos (or the DML completes)

This change releases admission control resources as
soon as the query is complete rather than waiting
for the client.
