#### Discovery Filter

The Discovery Filter controller is used to implement the `discoverySelectors` field of `MeshConfig`. This controller reads `Namespace`s in the cluster to determine if they should be "selected". Many controllers consumer this filter to only process a subset of configurations.

#### Multicluster

  // e.g. `meta.k8s.io/v1.DeleteOptions` or `meta.k8s.io/v1.CreateOptions`. This may be
  // different than the options the caller provided. e.g. for a patch request the performed
  // Operation might be a CREATE, in which case the Options will a
  // `meta.k8s.io/v1.CreateOptions` even though the caller provided `meta.k8s.io/v1.PatchOptions`.
  // +optional
  optional k8s.io.apimachinery.pkg.runtime.RawExtension options = 12;

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

And if you declared a `response_model`, it will still be used to filter and convert the object you returned.

        return packageViewDescriptor.memberScope.getContributedDescriptors(DescriptorKindFilter.ALL, nameFilter = { it == name })
            .asSequence()
            .filter { it.name == name }
            .mapNotNull { it.toKtSymbol(analysisContext) as? KtCallableSymbol }
    }
