Migration Plugin

rpm_unsigned repo exists, drpm does not.

Migration Plan:

{ "plan": {
  "plugins": [
    {
      "type": "rpm",
      "repositories": [
        {
          "name": "rpm_unsigned",
          "repository_versions": [
            {
              "pulp2_repository_id": "rpm_unsigned",
              "pulp2_distributor_repository_ids": [ "rpm_unsigned", "drpm" ]
            }
          ]
        }
      ]
    }
  ]
}}

Result (see the description, it should have onlt drpm there):
