Subject: [PATCH] spec: Automatically turn on cgconfig service

A number of the libvirt APIs require the use of cgroups. This is not
enabled by default on a RHEL6 install. After discussion with cgroups
team, it was decided that upon installation of the libvirt RPM, we
should automatically turn on the cgroups service. This will activate a
default configuration that turns on all cgroups controllers libvirt
requires for full operation.
