KUBE: kubemeta: create deployment scripts

[sdorr0]

kubemeta, a new application that gathers and kubernetes metadata in a friendly event driven, asynchronous way, needs to have deployment support built out for it.

This includes actions to generate container images, storing those images in appropriate repositories, and kubernetes yaml file support for deploying those images into a customer's kubernetes cluster.

The deployment scripts will be added to the https://github.com/kentik/kappa-cfg repo to give someone the ability to deploy kappa, kappa-agg, and kubemeta into a cluster with a single command.

Also, allow the scripts enough flexibility to deploy just a single app.

Two things to do before we close this out:

• Add something to kubemeta deployment manifest so latest image from dockerhub gets used on fresh installs
• Test against GCP and Azure envs

GCP works
