  - Create network service with cluster API

    Creates a new network customization and configuration
    service.  Seed it by moving the cluster-provider and
    cluster API from the orchestrator service to this new
    service.  More APIs to follow.
    Just put a Dockerfile in the ncm/scripts directory for now.
