Feature description

The LifecycleNode class is missing several parameter-related templates that are present in the regular Node class, such as get_parameter_or, get_parameter_or_set, and set_parameter_if_not_set. Adding the missing templates would allow a lifecycle node to be equivalent to normal nodes in its parameter-handling functionality, making it easier to port from a Node to a LifecycleNode.

Implementation considerations

Should be able to copy/paste the templates from the Node header.
