This rather large update adds the following
- A golang build container used for building golang executables and/or
  containers.
- envoyd, a daemon process that creates and updates the envoy config
  file based on consul's KV store and forces envoy to reload the config
  as it changes.
- Dockerfile(s) and compose files that integrate envoy into the NBI call
  chain to load-balance device-to-core assignment.
- Several developer tools that help build and replace specific
  containers in a running cluster. This allows the build process to be
  separated from the run-time as it will be in production.
- NOTES: A command line needs to be added to envoyd because now the
  values are declared at the start of the file. This will be submitted
  in a subsequent commit along with a change toward a more object
  oriented implementation.

Addressed reviewer comments.
Addressed even more reviewr comments.

+# This script is for developers only. It will create tunnels between
+# the vm cluster and the installer's registry and between the voltha
+# vm and the installer's registry. This allows containers to be
+# pushed to the registry and pulled into the cluster allowing to rapidly
+# cycle between container development and deployment for testing without
+# having to re-build the entire installer and re-deploy the cluster.
