IMPALA-6583: Wait for non-empty catalog update at impalad startup

Currently an empty statestore catalog update would enable impalad to
begin compiling queries. It breaks many custom cluster tests. This patch
makes impalad wait for a non-zero catalog version.

Testing: test_single_coordinator_cluster_config is run in a loop for
several hours on both 2.x and master branch. Core tests are also run.
