util: use protobuf encoding for core k8s apis

For core K8s API objects like Pods, Nodes, etc., we
can use protobuf encoding which reduces CPU consumption
related to (de)serialization, reduces overall latency
of the API call, reduces memory footprint, reduces the
amount of work performed by the GC and results in quicker
propagation of objects to event handlers of shared informers.
