VOL-569: Create kubernetes deployment configuration for each voltha service
This update:
- renames all voltha images referenced in kubernetes deployment files
to the 'voltha-<component>' format
- adds the kubernetes deployment files for grafana, dashd, and shovel
- adds deployment files for an Ingress resource and an nginx-based ingress
controller to allow access to the Consul and Grafana UIs from outside
the cluster
Manifest file ingress/05-namespace.yml sets up a namespace 'ingress-nginx'
for all ingress-related resources. This file will be deleted once we move
all voltha components, including ingress, to a 'voltha' namespace.
Deployment instructions for the ingress resources are provided in README.md.
