Cockpit port change to -> 9090

Hey all, There's been lots of discussion (on IRC and elsewhere) about choice of our default port, currently 1001. That's an unregistered port, but it's very unlikely we could register it (doing so requires an IETF RFC). Fedora is the first distro we're packaged in "for real" ... and the Fedora Server WG has asked us to try and use a port that has less of a chance of conflicting with something else in the future. On the Cockpit side it's very important that we use a memorable port. In fact it's one of the few ports admins will be typing repeatedly over and over again. The one that looks appropriate is 9090, which is for "Web System Manager". It's pretty easy to remember and hopefully will be consistent with some other web based consoles for other OS's. Cheers, Stef
