ssl: Handle socket option inheritance when pooling of accept sockets is used
Implement a listen socket tracker process that holds the emulated socket options so that it is possible to implement a destructive ssl:setopts on SSL/TLS listen sockets without changing the options of the internal socket as we want that socket to have the internal socket option values.
