This spec proposes implementing containerized VNF. We choose
to use Kubernetes resources (ConfigMap, Deployment, Horizontal
Pod Autoscaler, Service, etc) to define a containerized VNF.
1. Add "configurable_properties" type in VDU node.
2. Support translate TOSCA to Kubernetes templates.
3. Add kubernetes infra driver to support CRUD containerized
VNF.
