To enhance our OAuth2.0 ACR offering AM should be able to map more than just authentication chains to specific ACRs.
Suggestion is to add support for the same mechanisms that are used in Transactional Authentication/Composite advices.
Specifically: Authenticate to Chain, Authenticate to Module, Authenticate to Tree, Authenticate to Auth Level.
An interface element for performing this mapping should be available in an appropriate place in the OAuth2.0 provider's settings. It may require its own tab.
