Remove meaningless logging on replica-manager startup

ReplicaManager logs some meaningless values at warning value.  An
example is:

    05 Jul 2013 22:56:52 (System) [] ReplicaManager   version: $Id$
    05 Jul 2013 22:56:52 (System) [] DCacheController version: $Id$
    05 Jul 2013 22:56:52 (System) [] resilientGroupName=ResilientPools

The final line erroneously includes a new line.

This patch simply removes all references to the $Id$, fixes the
resilientGroupName logging and demotes it to info-level.
