Bharath Vissapragada bb9121da77 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.
