Resources code extensively uses DeepCopy to prevent in-memory copy of
the resource to be mutated outside of the resource model.
Previous implementation relied on YAML serialization to copy the
machine configuration which was slow, potentially might lead to panics
and it generates pressure on garbage collection.
This implementation uses k8s code generator to generate DeepCopy methods
with some manual helpers when code generator can't handle it.
