Increase MPM thread limits for Apache

Browse Source 
As Apache now being used for multiple services (repo, keystone, horizon
and skyline), it makes sense to slightly increase threads limit in
order to not face connectivity issues while HAProxy checks status,
fetching wheels or generic operations.

Hopefully, this will reduce intermittent failures while talking to repo
server or running tempest tests.
