File Support

I think this issue may be fixed by https://github.com/pulp/pulp/pull/3234

It looks like for every detail view you need to provide a manualschema. So for pulp_file sync it would look like:

diff --git a/pulp_file/app/viewsets.py b/pulp_file/app/viewsets.py

         importer = self.get_object()
         repository = self.get_resource(request.data['repository'], Repository)

This was temporarily reverted in https://github.com/pulp/pulp_file/pull/50. We need to redo this work once https://pulp.plan.io/issues/3420 is merged.
