BundleDeployment: add and implement required serviceAccountName and installNamespace fields

[joelanford]

Hacking a bit on rukpak BundleDeployment to put the following new required fields in the spec:

• installNamespace
• serviceAccountName

In the reconciler, I've removed all cluster-admin-like permissions and replaced them with just permission to create token requests.

I've also reorganized helm-operator-plugins a bit:

• Make the ActionConfigGetter capable of producing a different rest.Config per object
• Move health checks to the ActionInterface so that it uses the same rest.Config as the other helm interactions

Lastly, I've added a token getter/cache implementation and updated the setup of the controllers in rukpak's main.go files to use that for the actionConfigGetter configuration.

With all of that, I've run a few tests with permissions missing and with all permissions present, and things seem to work.

This is a WIP because nothing in helm-operator-plugins is merged, and I've pinned to my local copy that combines both of the above PRs.
