Function called after the HELLO was passed to the transport service.

Connect the given peers and call the callback when both peers report the inbound connection.

FIXME maybe schedule the application_validate somehow Initiate a connection from p1 to p2 by offering p1 p2's HELLO message

Remarks: start_peer's notify_connect callback can be called before.

Parameters

p1	peer 1
p2	peer 2
cb	the callback to call when both peers notified that they are connected
cls	callback cls

Returns
