Crate kube_runtime

Common components for building Kubernetes operators

This crate contains the core building blocks to allow users to build controllers/operators/watchers that need to synchronize/reconcile kubernetes state.

Newcomers are recommended to start with the Controller builder, which gives an opinionated starting point that should be appropriate for simple operators, but all components are designed to be usable á la carte if your operator doesn’t quite fit that mold.
