[HBASE-19073] Cleanup CoordinatedStateManager

• Type: Bug
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Fix Version/s: 2.0.0-alpha-4, 2.0.0
• Assignee: Apekshit Sharma
• Reporter: Apekshit Sharma

Description

• Remove the configuration hbase.coordinated.state.manager.class
• Keep following interface since they nicely separate ZK based
  implementation: SplitLogWorkerCoordination, SplitLogManagerCoordination,
  ProcedureCoordinatorRpcs, ProcedureMemberRpcs
• Replace CSM (interface) + BCSM (unnecessary middle hierarchy) with single
  CSM interface.
• Don't pass whole CSM object around (with server in it which gives acess to pretty much everything), only pass the relevant dependencies.
