Move remaining FCO in * sites to Transition

Please don't merge this without talking to me first. We should let the first site bed in at least for 12 hours if not over the weekend.

Following moving our first site to Bouncer, we want to start moving more traffic through Bouncer ahead of the UKBA launch.

This moves ~25,000 mappings for 161 sites.

This pull request excludes the primary FCO site which is higher traffic. These sites are each low traffic.
