stack updated HBASE-625:
------------------------

    Attachment: metrics-3.patch

This patch adds master metrics and adds to the regionserver UI publishing of regionserver metrics.

I need to test more.

Also want to think if a better way of getting store level metrics than getting synchronization lock on the online regions and then iterating over all stores and per store over synchronizing on the regions store Collection.

> 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).
