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.
However, this means anytime a workload changes (often), we need to update the policy.

Instead, the opposite was chosen: each workload will list the policies that select it.
