Ansible Plugin

v3.serializers.CollectionVersionSerializer doesn't include distro base_path in the 'download_url' it creates.

At the moment, since there is only one AnsibleRepository and one AnsibleDistribution, this doesn't cause a problem. But once we have multiple repositories, the 'download_url' will need to include the AnsibleDistribution.base_path in the url.

For example, with the galaxy_ng pr at https://github.com/ansible/galaxy_ng/pull/84/ it is possible to use per distro api endpoints.

For now, pr #84 has a local CollectionVersionSerializer that adds base_path to the 'download_url' so the 'download_url' looks like:

"http://localhost:24816/pulp/content/alikins-stage-distro-base-path/alikins.collection_inspect.0.0.182.tar.gz",

That will allow galaxy_ng to provide download_urls for 'golden' distro artifacts and for other repos/distros.
