event_type: custom_resource_definition.EventTypeDefinition, the event
type the source will filter by.
parameters: dict, additional parameters to set on the source spec.
broker: str, name of the broker to act as a sink for the source.
target_service: str, name of the Cloud Run service to subscribe to the
trigger.
