[Linaro-validation] port forwarding updates in the lab

Hi all,

This shouldn't make any difference to anyone, but I've just updated our router configuration so that all http and https connections to the lab go from the router to linaro-gateway rather than control. I think all the virtual hosts have entries on linaro-gateway, but it's possible that some sites have stopped working -- so do let us know and it'll be a trivial fix.

If nothing seems to be broken, I'll remove the other virtual host and ssl configs from control early next week.

Cheers, mwh
