Container Support

I noticed that some schema version 1 manifests are missing in some cases. In syncing BusyBox there are some, but in syncing library/hello-world there are none. More details:

Create repo:

http POST http://localhost:24817/pulp/api/v3/repositories/ name=bar

(Save REPO_HREF)

Create remote:

http POST http://localhost:24817/pulp/api/v3/remotes/docker/docker/ name='library/hello-world' upstream_name='library/hello-world' url='https://registry-1.docker.io' policy='on_demand'

(Save REMOTE_HREF)

Sync:

http POST ':24817'$REMOTE_HREF'sync/' repository=$REPO_HREF`` mirror=False

Try to view schema v1 manifests:

http :24817/pulp/api/v3/content/docker/manifests/?repository_version_added=/pulp/api/v3/repositories/<id>/versions/1/ | jq -r '.results[] | select(.schema_version == 1)'

This query finds nothing. I am expecting to see two manifests.

I confirmed in Foreman with Pulp 2 that there are supposed to be two schema v1 manifests in library/hello-world. I also tried searching Pulp 3 for them by their digests and couldn't find them.
