Launched Helm templates should include a Docker secrets postrenderer

If a cluster does not have a dockerconfigjson secret linked for a specific registry, Porter should attach the registry credentials. Here is Kubeapp's implementation.

Hi @abelanger5, I would like to take this up if this is still relevant.

Hi @supra08, many thanks, but this issue should be closed! Sorry about that. The postrenderer was implemented in postrenderer.go.
