> Currently the server hart beat sends over server load and region loads.  This is used
to display and store metrics about a region server.  It is also used to remember the sequence
id of flushes.
> This should be moved into an HBase table.  
> * Allow the last sequence id to persist over a master restart.
> * That would allow the balancer to have a more complete picture of what's happened in
the past.
> * Allow tools to be created to monitor hbase using hbase.
> * Simplify/remove the heartbeat.
