[HBASE-7479] Remove VersionedProtocol and ProtocolSignature from RPC

• Type: Task
• Status: Closed
• Priority: Blocker
• Resolution: Fixed
• Fix Version/s: 0.95.0
• Component/s: IPC/RPC
• Hadoop Flags: Incompatible change, Reviewed
• Release Note: Remove versioning of rpc protocols. Going forward we will not rely on versioning but on the wriggle-room protobufs give us per method and on custom migration to handle cases that outside of method-based scope.

Description

Replace with an innocuous "Protocol" Interface for now. Will minimize changes doing a replacement. Implication is that we are no longer going to do special "handling" based off protocol version. See "Handling protocol versions" - http://search-hadoop.com/m/6k7GUM028E/v=threaded thread and HBASE-6521 for background.
