Add v2 node provider for accepting status updates

This allows the use of a built-in provider to do things  like mark a node
as ready once all the controllers are spun up.

The e2e tests now use this instead of waiting on the pod that the vk
provider is deployed in to be marked ready (this was waiting on
/stats/summary to be serving, which is racey).
