Send peers the remote IP we see on the connection

[TheBlueMatt]

We should implement the BOLT spec change from lightning/bolts#917. Its a bit tricky with our architecture since we don't manage the TCP sockets ourselves, but we can just have the user provide the address in the connection-accepted/connection-made calls into PeerHandler and go from there.

I would like to work on this. Please tell me where should I start?

[TheBlueMatt]

We'll want the outbound connection opening function in PeerHandler to take a new argument in the form of a NetworkAddress, and then we'll want to store it (maybe Option-aly) in the Peer struct, copying it into the Init message when we send that.

Thanks! I will look into this!

What will be the data type of NetworkAddress? Also do you want me to name the variable as NetworkAddress or something like their_Network_Address inside the Peer struct.

Sorry, I meant NetAddress (which is already a thing), not NetworkAddress.
