Code Issues Proposed changes

Fedora cgroups support. 

* modules/jenkins/manifests/cgroups.pp
* modules/jenkins/manifests/params.pp: Fedora separates the cgroups
management utilities into an additional package.

* modules/jenkins/templates/cgconfig.erb: Fedora already automounts
cgroups subsystems. Also, because of Red Hat bug 918951, swap
management doesn't work in Fedora 18.
