1. install command loads chart archive.
2. invokes helm api to transform the pkg/chart.Chart type
to it's proto model.
3. the client then establishes a connection to tiller.
4. sends InstallReleaseRequest, receives InstallReleaseResponse.
todo (for complete install):
- walk pkg/chart.{Values,Deps,Templates} types and populate proto
definitions for various apis/messages.
