#### 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.

// not as the type of a variable.
