This patch moves the oci-container-configuration and related
configuration records to (gnu services containers).
Public symbols are still exported for backwards
compatibility but since the oci-container-service-type will be
deprecated in favor of the more general oci-service-type, everything is
moved outside of the docker related module.
* gnu/services/docker.scm: Move everything related to oci-container-configuration
to...
* gnu/services/containers.scm: ...here.scm.
