Sets JUJU_ACTION_UUID when handling an action event, so that ops sets ActionEvent.id appropriately. The ID is loaded from state.next_action_id and set on the state.Action object, similarly to relations.
Also stops setting JUJU_ACTION_NAME outside of action events - mostly to simplify the code addition, but in my quick checks this is the case in Juju as well.
