Apekshit Sharma 664b6be0ef HBASE-18640 Move mapreduce out of hbase-server into separate module.
- Moves out o.a.h.h.{mapred, mapreduce} to new hbase-mapreduce module which depends
  on hbase-server because of classes like *Snapshot{Input,Output}Format.java, WALs, replication, etc
- hbase-backup depends on it for WALPlayer and MR job stuff
- A bunch of tools needed to be pulled into hbase-mapreduce becuase of their dependencies on MR.
  These are: CompactionTool, LoadTestTool, PerformanceEvaluation, ExportSnapshot
  This is better place of them than hbase-server. But ideal place would be in separate hbase-tools module.
- There were some tests in hbase-server which were digging into these tools for static util funtions or
  confs. Moved these to better/easily shared place. For eg. security related stuff to HBaseKerberosUtils.
- Note that hbase-mapreduce has secondPartExecution tests. On my machine they took like 20 min, so maybe
  more on apache jenkins. That's basically equal reduction of runtime of hbase-server tests, which is a
  big win!
