Pulp

Some of pulpcore tests rely on the pulp_file[0] and pulp_rpm[1] plugins. The problem is that this won't scale. As we add more features to pulpcore that are only used by a subset of plugins, this design will require us to install more plugins into pulpcore's CI.

We should decouple pulpcore tests from requiring plugins by introducing a test plugin that tests can use. This test plugin would contain a superset of all features that pulpcore provides.

Alternatively we could maybe leverage the plugin template to be this test plugin.
