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

This update:
- organizes all Voltha components under their own namespace, "voltha". If
  you have a script for deploying Voltha, then add namespace.yml at the top.
- adds host volume mounts for Consul's data and config directories
- fixes a bug in Envoy where it was aborting because it couldn't find Consul
  even though it was getting the Voltha assignments from Etcd.
