VOL-569: Create kubernetes deployment configuration for each voltha service

This update adds kubernetes deployment files for etcd. These files are not
yet production-ready; for example, the etcd deployment will have to be
augmented to support persistent storage. The files do work and enable the
deployment of the envoy and vcore services on kubernetes.
