HBASE-24765: Dynamic master discovery (#2314)
This patch adds the ability to discover newly added masters
dynamically on the master registry side. The trigger for the
re-fetch is either periodic (5 mins) or any registry RPC failure.
Master server information is cached in masters to avoid repeated
ZK lookups.

Updates the client side connection metrics to maintain a counter
per RPC type so that clients have visibility into counts grouped
by RPC method name.

I didn't add the method to ZK registry interface since there
is a design discussion going on in splittable meta doc. We can
add it later if needed.

README.txt

This module has proto files used by core. These protos
overlap with protos that are used by coprocessor endpoints
(CPEP) in the module hbase-protocol. So core versions have
a different name, the generated classes are relocated
-- i.e. shaded -- to a new location; they are moved from
org.apache.hadoop.hbase.* to org.apache.hadoop.hbase.shaded.
