Components & utilities necessary to hold room games

As of now, we have functionalities to

• create room
• join room
• fetch other users (userId & scores)
• save room records to database
• generate question sets (resolves Question set generation (room) #27 )
• request question sets from servers (resolves Request questions from the server #35 )
• submit answers to the server side
• server-side verification (resolves Submit the answer to the server for verification #33 )
• timeout (resolves Timeout bar to see how much time is used #37)
• progress tracking (to the level question index)
• automatic freeup
