Most notably, this is only L4 resources.

Most of the API is fairly straight forward.
However, one interesting aspect is how these policies associate with workloads.
Istio's AuthorizationPolicy has label selectors.
However, we intentionally do not send those as part of the Workload API, in order to keep the size low.

The obvious solution to this is to put the list of selected workloads into the policy itself.
