Description

Currently we do not allow more then 1000 runtime DbRelationships in EntityResolver [1] (see 'makeUniqueRelationshipName'). This number is arbitrary and is really just a side effect of the runtime rel name generation mechanism. And there are real cases reported when it is problematic.

So at the minimum we need to increase this limit, but ideally we should probably provide a better then O(N) mechanism for unique name generation here.
