Clark Boylan 33c744d923 Set connection limits on mirror apache workers
We've noticed that our mirrors will semi regularly have problems due to
old stale works. For example using old ssl certs or having connection
problems to round robin backend services. In all cases restarting the
service (killing old workers) seems to fix things. Try to force this to
automatically happen by setting a reasonable connection limit per worker
before we recycle them.

# ssl connections to round robin backend services have trouble. Restarting
# the workers so that they load up new info seems to fix this. Try and force
# that to happen regularly with a connections limit per worker.
