[freeze break request] Another attempt at fixing collectd on proxies/apache boxes

[Ricky Elrod]

SELinux is blocking collectd from connecting to apache on localhost.
Also our config was missing an Instance tag, which seems to be required,
at least on the rhel7 version of collectd-apache.

I'd like to have this working so we have apache graphs of the release
tomorrow. +1's?
