This I've been changing removing HSA. Instead I'm passing an ISA (this
patch adds a getConnection(isa) method).

bq. Review request for hbase.

bq. Summary
bq. -------
bq.
bq. This patch does not completely remove heartbeats. It unburdens the
heartbeat of control messages; now heartbeat is used to
bq. send the master load only (At most recent hackathon we had rough agreement
that we'd keep heartbeat to carry load)... if we miss some, no biggie.
bq.
bq. RPC version changed on HMasterRegionInfo since the regionServerStartup and
regionServerReport arguments have changed.
bq. We pass a String now instead of HServerAddress so this should help with
our DNS issues where the two sides disagree.
bq.
bq. Removed HMsg.
bq.
bq. HServerAddress as been sort_of_deprecated. Its in our API so can't remove
it easily (its embedded inside HRegionLocation).
bq. Otherwise, we don't use it internally anymore.
bq.
bq. HServerInfo is deprecated. Server meta data is now available in new class
ServerName and load lives apart from HSI now.
bq.
bq. Fixed up regionserver and master startup so they now look the same.
bq.
bq. New tests
bq.
bq. Cruft cleanup.
bq.
bq.
bq. This addresses bug hbase-1502.

> HBase currently uses heartbeats between region servers and the master,
> piggybacking information on them when it can. This issue is to investigate if
> we can get rid of the need for those using ZooKeeper events.
