This uses a rest.Config to bootstrap TLS for the http server, webhook
auth, and the client.
This can be expanded later to do other kinds of TLS bootstrapping. For
now this seems to get the job done in terms of what VK expects for
permissions on the cluster.

This refactors the v1 lease controller. It makes two functional differences
to the lease controller:
* It no longer ties lease updates to node pings or node status updates
* There is no fallback mechanism to status updates
This also moves vk_envtest, allowing for future brown-box testing of the
lease controller with envtest
