Puppet Environment importing doesn't seem to handle module removal/changing
fang64 in #katello hit an error where a change in a module was not properly imported into the environment:
1. Upload puppet module 'foo' with classes A, B, & C
2. Create a content and publish it to Library
3. upload a different puppet module 'foo' with classes X, Y, Z (or some subset of A, B, C)
4. Publish the new content view
Results: Under "Configuration" > Environments > Library Content View environment > Classes
the old puppet classes A, B, C will still be shown.
