Set order of steps for incoming connections

[Juansecu]

Set order of steps for incoming connections. The order is the following:

1. Connection to RTMP scope
2. Execute command getRoomSOName
3. Execute command join
4. Send message AvatarEnterScene

Requirements:

1. The previous mentioned steps must be saved and updated in Redis for every incoming connection.
2. If an incoming connection does not follow this order, the server must destroy it immediately.
3. This order must expire after 5 minutes. If the incoming socket does not follow these steps during the given amount of time, it will be impossible for it to connect with the server.
