Title: Check if python-software-properties is defined before attempting to define it.

python-software-properties may be defined by other modules, causing Puppet to fail. This adds a check to ensure we are not defining a package which was previously defined by another module.
It also adds an rspec-puppet test to verify the change in behavior.
