------------------------------------------------------
[~stillalex], improved patch that would only allow for abortion if the given
{{AggregatedPermissionProvider}} supported the targeted permissions,
essentially moving the test for abortion inside the {{doEvaluate}} blocks. test
patch reflects that by covering both cases:
a) the aborting provider supports the target permission -> doAbort is invoked
and the subsequent providers are omitted from the evaluation,
b) the aborting provider returns NO_PERMISSION -> doAbort is never invoked and
all providers take part in the evaluation.

> when aggregating multiple authorization models we currently have the ability
> to choose between CompositionType.AND and CompositionType.OR for the
> evaluation of effective permissions. In other words as soon as more than 1
> PermissionProvider is present for the evaluation the results of that
> evaluation are either combined in an AND or OR fashion.
> however, we currently lack the ability to stop or abort the evaluation if a
> given provider instance was 'sufficient' to determine if a given set of
> permissions is granted or denied.
> [~stillalex], let's discuss ideas and options on how we could achieve this.
