Subject: [rebootcontrol] WOL: Make UDP-Port and c2c discovery configurable

The port setting only applies to WOL-packets sent from the satellite
server.
Testing the reachability of client subnets between each other is usually
pointless, since a subnet that is reachable from another subnet can also
be reached form the satelitte server, unless some fancy firewall rules
are in place.
