Handle distributed queries when shards != data nodes
Handle distributed queries when shards != data nodes

Fixes #2272

There was previously a explict panic put in the query engine to prevent
queries where the number of shards was not equal to the number of data nodes
in the cluster.  This was waiting for the distributed queries branch to land
but was not removed when that landed.
