Cluster grow not showing locality

[Peter Stachowski]

The scenario tests for clusters are occasionally failing when doing a cluster-show after a cluster-grow. This seems to happen because the locality flag on the new instances takes a few seconds (sometimes) to populate. This results in a 'AssertionError: Cluster missing attribute locality.' error in the cluster grow test.

This should fix the gate errors in the Redis scenario run

    [fix gate] Cluster grow not showing locality

    The scenario tests for clusters are occasionally failing when doing a
    cluster-show after a cluster-grow. This seems to happen because the
    locality flag on the new instances takes a few seconds (sometimes) to
    populate. This results in a 'AssertionError: Cluster missing attribute
    locality.' error in the cluster grow test.

    The fix is to check all the instances for the server_group information
    instead of just the first instance.

    The cluster tests were also tweaked so they could be run separately.
