Umesh Agashe 07c38e7165 HBASE-16549 Added new metrics for AMv2 procedures
Following AMv2 procedures are modified to override onSubmit(), onFinish() hooks provided by HBASE-17888 to do
metrics calculations when procedures are submitted and finshed:
* AssignProcedure
* UnassignProcedure
* MergeTableRegionProcedure
* SplitTableRegionProcedure
* ServerCrashProcedure

Following metrics is collected for each of the above procedure during lifetime of a process:
* Total number of requests submitted for a type of procedure
* Histogram of runtime in milliseconds for successfully completed procedures
* Total number of failed procedures

As we are moving away from Hadoop's metric2, hbase-metrics-api module is used for newly added metrics.

Modified existing tests to verify count of procedures.
