SEC-2842: RoleHierarchyVoter should first filter ConfigAttributes received

Jordi Llach Fernandez (Migrated from SEC-2842) said:

If no ConfigAttributes are supported by the voter by letting RoleVoter.vote do its bussiness without prior filtering useless calls to extractAuthorities are done

I've just overriden RoleHierarchyVoter.vote, which really belongs to RoleVoter, as follows

@Override
public int vote(Authentication authentication, Object object, Collection<ConfigAttribute> attributes) {
  List<ConfigAttribute> sup = attributes.stream().filter(a -> this.supports(a)).collect(Collectors.toList());
     if (!sup.isEmpty()) return super.vote(authentication, object, sup);
     else                      return ACCESS_ABSTAIN; 
}

Start by locating RoleHierarchyVoter.vote and the RoleVoter.vote path that calls extractAuthorities, then inspect how ConfigAttribute support is checked. The change is complete when unsupported attributes do not trigger authority extraction and the voter abstains when no supported attributes remain; add or update coverage for both outcomes.
