Wrapper on top of Iterator representing a closable resource to the underlying storage.
This class also serves as a reference on how the providers can maintain a counter of the
underlying storage resources in their implementation. This counter in coordination with
gremlin-test suite can be used to detect cases when the query processor does not gracefully
release the underlying resources.
