Issue #13647 - Add ContainerLifeCycleMap

[afarber]

Fixes #13647

• Add ContainerLifeCycleMap<K, V extends LifeCycle> that implements Map while managing values as beans
• Values are automatically started/stopped with the container lifecycle
• Removal through keySet(), values(), entrySet() views also unregisters beans
• Add missing tests for AttributeContainerMap
• Update bean.adoc with documentation for both classes

@gregw I'm not against it, but I would like to understand where this is necessary, and update the relevant code to use this new class, otherwise it will be an unused class in the source tree.
