Add admin role check for messages from admin to socket connection

Description

Inside socket connection handler we have event "message:send".
Clinet can send isAdmin flag inside data.sender, so server needs to validate this.

socket.on('message:send', function (data) {
      const message = {
        id: nanoid(),
        body: data.body,
        sender: data.sender,
        date: Date.now()
      };
      history.emit('save', message);
      chatRoom.emit('message:received', message)
    });

Implementation

Client sends a token on connection opening via handshake.
So the best way I think is to get this token and if isAdmin flag present, validate inside event callback the role of user, by geting user id from token and check role from DB.

Requires advanced level of coding skills.
