Major Release:

This changes the Redis backend to use a SETNX-based lock (RedLock). This should address race conditions that the previous approach had (See: 7, 60).

*This may not be backwards compatible with existing keys stored in Redis.*
If you are upgrading from `1.0.0`, it may be safer to remove any previous used lock keys (See https://github.com/cameronmaske/celery-once/pull/67issuecomment-384281438 for instructions).

Other changes include:

- Able to run on blocking mode when scheduling tasks with Redis backend. See the README for more details.

- ``AlreadyQueued`` exception return's countdown seconds as `float` instead of `int`.

Big thanks to grjones for his contributions for this patch.
