Rule that creates a new `LifecycleListener` and associates it with the top object on the stack which must implement `Container` and `Lifecycle`. The implementation class to be used is determined by:

1. Does the top element on the stack specify an implementation class using the attribute specified when this rule was created?
2. Does the parent `Container` of the `Container` on the top of the stack specify an implementation class using the attribute specified when this rule was created?
3. Use the default implementation class specified when this rule was created.
