• A room can have multiple Live Polls, but only 1 can be active
  • room will get an entry 'livepoll', if null there's no active livepoll
  • room will get an entry 'livepollHistory' for all Live Poll's that are NOT active (past live polls)
• ws-livepoll.service, will send a stream of live poll results, when provided with an active Live Poll. The payload is number[]
