that just changes the address we bind to. LIBPROCESS_IP and LIBPROCESS_PORT semantics could
be left untouched.

If 2 libprocess based unix processes are running, they would point to a different <public_ip:public_port>
(most likely same public_ip but a different public_port, ie. same LIBPROCESS_PUBLIC_IP but
a different LIBPROCESS_PUBLIC_PORT). The processes themselves would bind as it does today
on <ip:port> (based in LIBPROCESS_IP and LIBPROCESS_PORT). Once a request lands on a
corresponding <public_ip:public_port>, a proxy listening on that would forward that
to the actual <ip:port> corresponding to the <public_ip:public_port>.

As an example, mesos-master binds on 10.11.12.13:5050 (ip:port) with public_ip:public_port
as 192.168.100.100:6050, and say scheduler binds on 10.11.12.13:8081 with public_ip:public_port
as 192.168.100.100:9081. Requests received on 192.168.100.100:6050 shall be proxied over to
10.11.12.13:5050 (to reach mesos-master) and requests received on 192.168.100.100:9081 shall
be proxied over to 10.11.12.13:8081 (to reach scheduler).
