feat(engine): add recursive template resolution

feat(tiller): add initial tiller client for basic helm installs.

feat(helm): add local chart repository workflow spike

  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.
