koji_hub: switch to event workers in apache and bump limits way up.

Browse source 
By default apache uses prefork and a limit of 250. It's possible that this limit was
the thing causing us issues over the last week. This moves to the event mpm and ups limits
a lot. It also needs to up limits on db connections or the increased workers will just
cause the db server to overload.

With this setup, builders are no longer dropping out, but it's not clear if it's solved
all the issues we have been seeing.
