s4-replicated_objects: Implement a mechanism to relax some attributes conversion

Browse Source 
during replicated object convert stage.
The problem is that we may have loops in schema graph and we can't
resolve those loops in just one pass. Ignoring some attributes
conversion will allow us to have a functional schema cache that we
can use later to resolve all attribute OIDs on another pass
