Coordinator-only queries get queued when there are no executor groups

      Description

      Reproduction:

      tarmstrong@tarmstrong-box:~/Impala/incubator-impala$ start-impala-cluster.py -s1 --use_exclusive_coordinators;
      [localhost:21000] default> select * from tpch.lineitem order by l_orderkey limit 5;
      ERROR: Admission for query exceeded timeout 60000ms in pool default-pool. Queued reason: No healthy executor groups found for pool default-pool.
      [localhost:21000] default> select 1;
      ERROR: Admission for query exceeded timeout 60000ms in pool default-pool. Queued reason: No healthy executor groups found for pool default-pool.
      

      I expected that the second query should run immediately since it doesn't actually need to be scheduled on any executors. I suspect this may be a regression from the executor group changes, but didn't confirm.
