Code fixes

[VatsalBhuva11]

Small fixes;

• Only the room's creator should be able to update the room name and description, and remove other users from the room
• Hence, create a separate controller to allow a logged in user to disconnect themselves (route should be /api/v1/room/user/disconnect
• Also change the /api/v1/room/user/delete route to /api/v1/room/user/remove for better semantics (explains the action of one person, here the room creator, removing someone and not deleting them).
  It's not competitive, as it's quite easy
