Remove split commit and some deprecated config for real-time protocol on controller

[Jackie-Jiang]

• Removed config of disabling split commit on controller (server can still decide whether to use split commit, but controller should support both)
• Removed config of allowing HLC table on controller
• Removed deprecated offset from controller protocol response
