This fixes indentation, documentation, and removes unused protobuf
files.

This adds support for dry run on install, as well as providing
enough info for an install to display (verbose) manifests. While
doing this, I ended up just storing the rendered manifests for
simplicity.

	1. remove preliminary hapi protocol buffer definitions
	2. modify hapi Makefile
	3. update hapi protobuf model in _proto/hapi/{chart,release,services}
	4. generate protobuf src to pkg/proto/hapi/{chart,release,services}
