API url for returning list of containers was wrong

In a restful API, the URL for a particular resource should always be the URL.

GET /api/v1/container - should return a list of container (old url was wrong, had an s on the end)
GET /api/v1/container/{name} - should return detail for a particular container (this was ok)
POST /api/v1/container - should create a new container (..ok)
PUT /api/v1/container/{name} - should update a given container (ok)
DELETE /api/v1/container/{name} - should delete a given (ok)

So only really the URL that returned a list of containers was wrong.
