Deploy Helm Tiller into Kubernetes cluster
Note: General design for applications discussed in #38464.
We plan to use Helm as the primary tool for deploying and managing assets in a Kubernetes cluster. (#35616)
This will likely need to be one of the first things we do when working with a cluster, as deploying things like Prometheus will depend upon tiller already being there.
In order to achieve this, we are scheduling an installation POD inside the cluster which can run
helm CLI in a safe environment.
