> hbase should write loadings on a period in a format that is amenable to tools like ganglia
(rrd).  Master can dump cluster loadings and averages.  Regionservers would report their own
loadings.  Should exploit the work up in hadoop for doing this kinda thing (GangliaContext)
where it makes sense.  Extra browning points if user can optionally enable display of graphs
in the hbase UI (JRobin).
