Changes in klog and logr have made automatic bumps from dependabot
problematic.
We also shouldn't need klogv1 so removed that.

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
