[Freeze Break] Remove app05-08 for pkgdb

We've been seeing intermittent timeouts with a particular long running pkgdb
url.  In an attempt to narrow down where the problem is coming from we'd
like to remove sending pkgdb requests to app05-app08.  Those are backup app
servers that don't live in phx so the latency for them to talk to the db
server is high.  For this particular page, it takes around 35s to get the
page from app01-04.  It takes 2.5-3.5 minutes (roughly) to get the page from
app05-08.

We somewhat expect that the problem will continue but doing this will allow
us to eliminate the non-phx app servers as the source of the timeout.

Could I get two +1's for the following change?
