This starts the work of having a `NodeProvider` which is responsible for providing node details. It splits the responsibilities of node management off to a new controller. The primary change here is to add the framework pieces for node management and move the VK CLI to use this new controller. It also adds support for node leases where available. This can be enabled via the command line (disabled by default), but may fall back if we find that leaess aren't supported on the cluster.
