code review: HBASE-7268 correct local region location cache information can be overwritten w/stale information from an old server

Hi,
Please take a look at HBASE-7268 where fix for preventing stale location
information from overwriting region location cache is proposed.
This is an incompatible change - we are introducing a new column in .META.
table, tentatively named 'openseqnum'.
This column stores the latest sequence Id for the underlying region when
region is opened.

Please provide your opinion on the approach.

Thanks
