Note that this could in theory be removed (and probably applies to other controllers) except for this line - https://github.com/Katello/katello/pull/3985/files?utm_campaign=website&utm_source=sendgrid.com&utm_medium=email#diff-bd067e942d8b91e91010e4f05c8034f5L78

I debated changing that line to `GpgKey.create!` but found that I would have to edit the model layer and/or potentially the UI parameters passed in order to allow creation by way of just an `organization_id`.
