UnattendedController makes DB queries for TemplateKinds in the class scope to define methods and set up action filters. This bad style causes a problem in foreman_bootdisk which adds a method chain to the provision method in the class. When running tests under Rails 4, if the controller's instantiated too early, the right methods aren't defined.

  4) Error:
UnattendedControllerTest#test_0002_should get a kickstart even if not using the first NIC:
AbstractController::ActionNotFound: The action 'provision' could not be found for UnattendedController
    test/functional/unattended_controller_test.rb:43:in `block in <class:UnattendedControllerTest>'

Changing this to make queries when it's called would create more testable code both in core and the plugin.
