Bharath Vissapragada 8126566b27 HBASE-23281: Track meta region locations in masters (#830) 
* HBASE-23281: Track meta region changes on masters

This patch adds a simple cache that tracks the meta region replica
locations. It keeps an eye on the region movements so that the
cached locations are not stale.

This information is used for servicing client RPCs for connections
that use master based registry (HBASE-18095). The RPC end points
will be added in a separate patch.

README.txt 

Apache HBase [1] is an open-source, distributed, versioned, column-oriented
store modeled after Google' Bigtable: A Distributed Storage System for
Structured Data by Chang et al.[2]  Just as Bigtable leverages the distributed
data storage provided by the Google File System, HBase provides Bigtable-like
capabilities on top of Apache Hadoop [3].

To get started using HBase, the full documentation for this release can be
found under the doc/ directory that accompanies this README.  Using a browser,
open the docs/index.html to view the project home page (or browse to [1]).
The hbase 'book' at http://hbase.apache.org/book.html has a 'quick start'
section and is where you should being your exploration of the hbase project.

The latest HBase can be downloaded from an Apache Mirror [4].

The source code can be found at [5]
