Changelog:
==========
- Fix bug in redis version parsing when using Elasticache or any other that
sends major/minor. redis-py incorrectly parses these as floats because
there's only a single decimal, so the version check was breaking.
- Rename max task option --max-tasks (previously was --max_tasks).
