CON-223: Removed max_objects_per_thread API (#60)

* CON-223: Removed max_objects_per_thread API

The behaviour of max_objects_per_thread has changed in the core, and it now
grows dynamically, meaning we no longer need to provide a way of setting it.

* CON-200: Add test

* CON-223: Added empty implementation of deprecated API
