* PoolMap does not discard any elements anymore. If an element is put,
it always stores it. The reason: it stores expensive resources (rpc
connections) which would lead to resource leak if we simple discard it.
RpcClients can reference netty ByteBufs which are reference counted.
Resource cleanup is done by AbstractRpcClient.cleanupIdleConnections().
* PoolMap does not implement Map interface anymore, so ensuring
thread-safety has become easier. Put method is replaced with getOrCreate().
* ThreadLocalPool doesn't use ThreadLocal class anymore. It stores
resources on thread basis, but it doesn't remove values when a thread
exits. Again, proper cleanup is done by cleanupIdleConnections().

src/main/asciidoc/_chapters/architecture.adoc
Clean up the read replica of META doc. Introduce the new read replica
liveness on META and the new 'LoadBalance' feature (with warnings).
General edit.
It adds load balance support for meta lookup in AsyncTableRegionLocator.
The existing meta replica mode is renamed as "HedgedRead", client sends scan request to the primary meta replica region first,
if response is not back within a configured amount of time, it will send scan requests to all meta replica regions and
take the first response. On top of the existing mode, a new mode "LoadBalance" is introduced. In this mode, client first
choose a meta replica region to send scan request. If the response is stale, it may send the request to another meta replica region or
the primary region. In this mode, meta scan requests are load balanced across all replica regions with the primary mode as
the ultimate source of truth.
Two new config knobs are added:
1. hbase.locator.meta.replicas.mode
Valid options are "None", "HedgedRead" and "LoadBalance", they are case insensitive. The default mode is "None".
2. hbase.locator.meta.replicas.mode.loadbalance.selector
The load balance alogrithm to select a meta replica to send the requests.
Only org.apache.hadoop.hbase.client.CatalogReplicaLoadBalanceReplicaSimpleSelector.class
is supported for now, which is the default as well. The algorithm works as follows:
a. Clients select a randome meta replica region to send the requests if there is no entry for the location in the stale
location cache.
b. If the location from one meta replica region is stale, a stale entry will be created in the statle location cache
for the region.
c. Clients select the primary meta region if the location is in the stale location cache.
d. The stale location cache entries time out in 3 seconds.
If there is no "hbase.locator.meta.replicas.mode" configured, it will check the config knob "hbase.meta.replicas.use".
If "hbase.meta.replicas.use" is configured, the mode will be set to "HedgedRead".
Prior to this patch hbase always used the MD5 hash algorithm to store a hash for encryption keys.
This hash is needed to verify the secret key of the subject. (e.g. making
sure that the same secrey key is used during encrypted HFile read and write).
The MD5 algorithm is considered weak, and can not be used in some
(e.g. FIPS compliant) clusters.
In this patch we:
- add a config parameter to globally enable/disable column family encryption (def enabled)
- introduce a backward compatible way of specifying the hash algorithm.
This enable us to use newer and more secure hash algorithms like SHA-384
or SHA-512 (which are FIPS compliant).
- add a config parameter to fail if an hfile is encountered that uses a
different hash algorithm than the one currently configured to ease validation after
migrating key hash algorithms (def disabled)

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.
