Extend payload with request data from event

[atompie]

Describe the bug

This is an error in scheduler plugin and requires rebuild of GRPC stubs. We need to extend payload with request data from event.

    async def schedule(self, schedule_at, callback_host, source_id, profile_id, session_id, event_type, properties, context):
        # todo extend payload with request data from event
        message = pb2.Payload(
            time=schedule_at,
            callback_host=callback_host,
            source_id=source_id,
            profile_id=profile_id,
            session_id=session_id,
            event_type=event_type,
            properties=self._to_struct(properties),
            context=self._to_struct(context)
        )
