lnwire: modify NetAddress to implement the net.Addr interface
This commit modifies lnwire.NetAddress by adding a .Network() method.
With this added method the struct now implements the net.Addr interface
meaning that it can now be transparently passed into any context where
a net.Addr is requested.

This change paves the way to integration of btcd’s new connmgr into the
daemon to handle establishing persistent connections to all channel
counter parties.
