Container Support

Original:

In each of their generated docs I noticed the endpoints all looked like

**POST** /docker/blah

instead of

**POST** /pulp/api/v3/blah

. Also, when doing DockerRecursiveAddApi.create I get a 404 and

No route matches [POST] "/docker/recursive-add"

at

lib/pulp_docker_client/api_client.rb:81:in `call_api'

However, it looks like the schema is actually correct, but the urlmatching is not strict enough.

All of these are valid and routed to the same view:

http POST localhost:24817/docker/recursive-add/ repository=/pulp/api/v3/repositories/597c2209-2ff2-4eec-b476-3740ff2879de/
http POST localhost:24817/pulp/api/v3/docker/recursive-add/ repository=/pulp/api/v3/repositories/597c2209-2ff2-4eec-b476-3740ff2879de/
http POST localhost:24817/thanks/for/reading/the/details/docker/recursive-add/ repository=/pulp/api/v3/repositories/597c2209-2ff2-4eec-b476-3740ff2879de/

IIRC, this is actually a deliberate feature of the plugin api, so they can register non-prefixed endpoints like /v2/ for Docker.

This might just be as simple as adding "^pulp/api/v3/" to the start of the urlpatterns, but it will need to be done for any plugins that have implemented custom urls.
