Testing against redis instances directly (dynomite replication does not seem to be working so no need for the extra layer at this point) and observed that once a node goes does (e.g. restart) dyno will not recover.  The connection is "broken" and there is no logic to repair the connection. Added logic to close and reopen upon broken pipe.  Also noticed that the error count w/in heath tracker is not reset upon success.  Although this might be desirable I decided to allow the reset.
