Currently we abuse openingd and dualopend to do this, but connectd already
has the ability to talk to peers, so it's more efficient.

This matters: if we connected, the address is probably usable for future connections.
But if they connected, the port is probably not (but the IP address may be).
Changelog-Added: JSON-RPC: `connect` returns "direction" ("in": they iniatated, or "out": we initiated)
Changelog-Added: plugins: `peer_connected` hook and `connect` notifications have "direction" field.

This is simple, and we now can multifundchannel to every node on testnet
(one simply hangs once we connect).
Changelog-Fixed: Protocol: We now hang up if peer doesn't respond to init message after 60 seconds.
