mod_s2s: Distinguish between high and low level errors in bounces
`remote-server-not-found` is reported for problems occurring without a
reply `<stream>` having been opened, e.g. DNS records were not found or
no TCP stream could be established to a functioning XMPP entity.
`remote-server-timeout` is reported for problems that occurring after a
stream has been opened, such as configuration problems, inability to
perform TLS or unsuccessful certificate validation.
