410296:  compendium docs outdated

Updated with regard to spring version updates
Updated links to external resource where possible
Removed ancient references to pre-gemini
resources where applicable

Applied documentation contribution:
Current documentation features outdated information
on cm update attributes. The 'update-strategy'+'update-method'
attributes were replaced by 'autowire-on-update'+
'update-method' attributes and their behavior has
changed accordingly.
