This adds POST and DELETE support for a 'secrets' sub-resource on the
containers resource. This will allow a user to add or remove secret
references to an existing container. Only generic containers are
supported per the blueprint for this feature.
If a secret reference already exists in the container, an appropriate
error will be returned indicating that the secret already exists in
the container. I chose this approach over silently accepting the
update, as the name for the container secret could change, so a delete
and re-add seems to be the safer option if a user just wants to change
the name, which is not something that I see happening too often.
Additionally, the action is a POST and not a PUT, so it shouldn't
really update an existing resource.
