Pulp

There are SELinux denials in the log after syncing a pulp_file importer.

To reproduce:
1. Modify the stubbed file plugin. It defines `sync`, but it is `NotImplemented`. Override the function and add a log message. https://github.com/pulp/pulp_file/blob/0518201f3e0bd6cbf85b79b87afc2f05abe69fbf/pulp_file/app/models.py#L29
2. Using the browseable web API, create a repository
3. Create an importer with (related to the repo you just made). Make sure it has something in the feed field.
4. sync the importer.
