We now have a base test case class for Predis (namely PredisTestCase)
grouping various commonly used utility methods shared by all of the
tests in the suite, greatly improving reusability.
This iterator tries to mimic the same behaviour of the cursor-based
iterators implemented upon the SCAN family of commands and offering
only limited guarantees on the returned elements, but uses LRANGE to
fetch items from a list incrementally.
