feat: bootstrap tiller with host network

[mark-burnett]

Is this a bug report or feature request? (choose one): feature request

I would like to use Armada to bootstrap and manage tiller. This means writing a tiller chart, which controls a deployment and service account/RBAC credentials for tiller.

Additionally, since I would like to manage CNI via a chart, I would like the ability to create the initial tiller pod with host networking mode. Smooth bootstrap will probably require faking the pod spec hash label/annotation that kubernetes applies to deployment managed pods.
