Refactor Helm deployments (#341)

Browse source 
* Wrap KMS deployment in one main chart that
deploys all other services. Other services will follow.
* Use .tgz via helm-package as serialization format
* Change Release type to carry chart as byte slice
* Remove KMSConfig
* Use json-schema to validate values
* Extend release.md to mention updating helm charts
