Freeze break: update sudoers

Greetings. I'd like to add the new 'busgateway01.stg.phx2.fedoraproject.org' to sudoers in the WEB group (so sysadmin-web can sudo on it). This is a pretty low impact change, but sudoers is global, so it would update on all hosts. Would fix ticket: https://fedorahosted.org/fedora-infrastructure/ticket/3442 No diff since its a change in private repo, but it's just adding that host to one line for web group. +1s? kevin
