Really chat with users and invite another user into chatting room.
Detailed work content
It's time to really test if users can chat each other with web socket.
I'll summarize the process of how to chat each other.
User A search user B with his chattting ID and chat first.
User B get message from A and enter the room.
Whether User B like it or not, once User A send message to B, It must be sent to User B. He can choose to banish him or not.
(That means chatting room can be made when user just send message at first)
They can invite another user to their chatting room. They search user ID and invite him and send message.
