This patch describes the way to install Kubernetes VIM via Devstack and register Kubernetes VIM in Tacker. Tacker reuses the efforts from Kuryr-Kubernetes project to create Kubernetes cluster. This patch also sets up native Neutron-based networking between Kubernetes and OpenStack VIMs to connect VM based and container based VNFs together, that bring hybrid deployment SFC in the future. Partially Implements: blueprint kubernetes-as-vim Change-Id: Idf04f012c6daf93a33ad89a5a7c737f3668eb405
