Added test-kitchen and Berkshelf configuration which for easier testing.
This config only comes into play if a developer is using test-kitchen
and/or berkshelf.  Also cleaned up some style issues that were reported
by foodcritic.  Lastly I created two custom sumo.json files that set up
the correct syslog and secure file followers for debian family and rhel
family operating systems.  Anything that doesn't fall into those two
pretty big buckets ends up using the default sumo.json template.
Uncommented cleanup recipe and updated sumo.json template to use
platform_family for rhel and debian distro's.
Updated .kitchen.yml to only ubuntu 12 and centos 6.4 baseboxes.
Additional boxes can be added by developers for wider testing base.
Merge pull request #2 from rayrod2030/master

Test-kitchen/berkshelf integration plus saner default sumo.json files for debian and rhel platform family
