Create Accepted AccessDelegationRequest instead of ACL

If a LogisticsObjet is created via a POST endpoint with public=true, e.g. POST http://localhost:8080/logistics-object?public=true", then an automatically accepted AccessDelegation should be created instead of an ACL entry. This makes it possible to control access via revoke/update AccessDelegationRequest.

The same should be applied if authorize-creator setting is set to true.
