go.mod: update kubernetes to v1.22.0

This brings in some cri api changes for cgroups, Windows pod sandbox security
context changes and some new fields for the Windows version of a privileged
container.

This also unfortunately bumps the prometheus client, grpc middleware, bolt
and klog :(

 common patterns: auth, logging, message, validation, retries or monitoring.
 
 These are generic building blocks that make it easy to build multiple microservices easily.
