Title: DSL: remove support for `nested_container`

Obsoleted by new form `container :nested`.

This PR only removes DSL support; the job is incomplete. Internally, `container :nested` is still implemented as a pseudo-artifact named `nested_container`. The intention is to factor nested containers out of artifacts.
