[HBASE-19048] Cleanup MasterObserver hooks which takes IA private params

• Type: Sub-task
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Fix Version/s: 2.0.0-alpha-4, 2.0.0
• Component/s: Coprocessors
• Hadoop Flags: Reviewed

Release Note

Purged InterfaceAudience.Private parameters from methods in MasterObserver.

preAbortProcedure no longer takes a ProcedureExecutor.

postGetProcedures no longer takes a list of Procedures.

postGetLocks no longer takes a list of locks.

preRequestLock and postRequestLock no longer take lock type.

preLockHeartbeat and postLockHeartbeat no longer takes a lock procedure.

The implication is that that the Coprocessors that depended on these params have had to coarsen so for example, the AccessController can not do access per Procedure or Lock but rather, makes a judgement on the general access (You'll need to be ADMIN to see list of procedures and locks).
