Adding special semantics for existing options generally ends up being
a bad idea in retrospect.

Inverse boolean options are also not very desirable.

I'd suggest a "auto-connect-ports" boolean option, which defaults to
enabled.


 - auto-connect-ports == true,  connect-ports= <unset>

    => use the proposed default regex for connect ports

 - auto-connect-ports == true, connect-ports = regex

    => use the connect-ports regex

 - auto-connect-ports == false, connect-ports= <unset>

   => don't auto connect at all

 - auto-connect-ports == false, connect-ports=regex

   => logically inconsistent config, report an error
