Implement monitor(Socket)

[obi458]

Is your feature request related to a problem? Please describe.
I'm always frustrated when I have to monitoring a socket returned from :listen, handshake or connect.

Describe the solution you'd like
Is it possible to integrate in OTP the function monitor(Socket) like sockname(Socket)?

Describe alternatives you've considered
Currently, on new main version, we have to inspect sockname and write our own monitor function.

Why do you want to monitor the sslsocket() ? The controlling process will receive a close message it the underlaying socket is closed.
And for passive mode API functions calls will return error closed if the socket is no longer available.

We tag each socket with a label and create a report(connectime,disconnecttime and so on) for the user.
