Updated testkitchens to the latest distro versions
Fixes the rpm repo links for centos and fedora
Uses the proper RPM keys on Redhat and Fedora
Adds some package dependencies for the redhat test
Enables fedora testing

FC18 put the SATA drives before the boot drive, so I moved them onto the same IDE controller
FC19 has a node.platform_family of '', so it fails
FC20 doesn't have ceph packages yet

The FC18 test fails after completely running, because the OSDs don't start due to a lack of udev hook
Running ceph-disk-activate manually works and starts the OSDs and makes the cluster healthy
Adds Debian Wheezy tests

It passes its test perfectly
Fixes style guide violation with the redhat fixes
Don't try to install btrfs-tools on rhel5
