Support for AuthorizationManager Spring Security API

[thaarbach]

As mentioned in https://docs.spring.io/spring-security/reference/whats-new.html#_authorization the AccessDecisionManager is deprecated an will be removed in futher versions of Spring Security.

Is there a plan to support newer Versions of Spring Security?

An AccessDecisionManager and it dependency like AccessDecisionVoter etc. are used in SecurityFlowExecutionListener.
