You can disable this with `fetchinvoice-noconnect`. Changelog-EXPERIMENTAL: We will now reply to invoice_request messages even if reply path requires us to make an outgoing connection (LDK does this) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Our fetchinvoice always creates a reply path which terminates at their peer, so we need a dev overrride for that. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Currently, anything which doesn't have a live channel is considered transient. We free this first under stress, and also if they're still connecting. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Requires a hack to exhaust connectd fds and make us close a transient. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

This is vital for LDK interop! They give us a reply path which isn't an immediate peer.
So we do that. Now we have to handle the case where an attacker makes us open many connections, so we demark these in connectd as "transient" so it knows to throw them away under stress.
Closes: #7110
