New tool to dump existing replication peers, configurations and
queues when using HBase Replication. The tool provides two flags:
--distributed This flag will poll each RS for information about
the replication queues being processed on this RS.
By default this is not enabled and the information
about the replication queues and configuration will
be obtained from ZooKeeper.
--hdfs When --distributed is used, this flag will attempt
to calculate the total size of the WAL files used
by the replication queues. Since its possible that
multiple peers can be configured this value can be
overestimated.

This is a revert of a revert; i.e. we are adding back the change only adding
back with fixes for the broken unit test; was a real issue on a test that
went in just at same time as this commit; I was getting a new nonce on each
retry rather than getting one for the mutation.
Other changes since revert are more hiding of RpcController. Use
accessor method rather than always pass in a RpcController
Walked back retrying operations that used to be single-shot (though
code comment said need a retry) because it opens a can of worms where
we retry stuff like bad column family when we shouldn't (needs
work adding in DoNotRetryIOEs)
Changed name of class from PayloadCarryingServerCallable to
CancellableRegionServerCallable.
Fix javadoc and findbugs warnings.
Fix case of not initializing the ScannerCallable RpcController.
Below is original commit message:
Remove mention of ServiceException and other protobuf classes from all over the codebase.
Purge TimeLimitedRpcController. Lets just have one override of RpcController.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/AbstractRegionServerCallable.java
Cleanup. Make it clear this is an odd class for async hbase intro.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/HTable.java
Refactor of RegionServerCallable allows me clean up a bunch of
boilerplate in here and remove protobuf references.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
Purge protobuf references everywhere except a reference to a throw of a
ServiceException in method checkHBaseAvailable. I deprecated it in favor
of new available method (the SE is not actually needed)
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/PayloadCarryingServerCallable.java
Move the RetryingTimeTracker instance in here from HTable.
Allows me to contain tracker and remove a repeated code in HTable.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/RegionServerCallable.java
Clean up move set up of rpc in here rather than have it repeat in HTable.
Allows me to remove protobuf references from a bunch of places.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/FlushRegionCallable.java
Make use of the push of boilerplate up into RegionServerCallable

Move boilerplate up into superclass.

Cleanup

Factor in TimeLimitedRpcController. Just have one RpcController override.
D hbase-client/src/main/java/org/apache/hadoop/hbase/ipc/TimeLimitedRpcController.java
Removed. Lets have one override of pb rpccontroller only.

(handleRemoteException) added
(toText) added
