Python 2 compatibility and redis fixes.

[BillSchumacher]

Fixed - Issue where it would attempt to import redis in the store/redis.py overlapping naming...
Fixed - super() calls.
Fixed - An issue where py2 didn't like the class being the same type as renamed parent. Hence BeatXScheduler rename.
Fixed - Import urllib urlparse.
Fixed - Travis CI for Py2
Added - mock requirement for Py2
Added - Uppercase config detection, resolves #3.

You have to squash them when you merge it in. I don't have merge permission.

Should resolve #3 now, this threw me off for a moment as well.

Should probably note this will break old configurations. Config needs to be updated to: celery_app.config_from_object({
# ...
'beat_scheduler': 'beatx.schedulers.BeatXScheduler',
'beatx_store': 'redis://127.0.0.1:6379/',
# ...
})

Config using celeryconfig.py obj::

CELERYBEAT_SCHEDULER = 'beatx.schedulers.BeatXScheduler'
BEATX_STORE = 'redis://127.0.0.1:6379/

Hi!
Sorry for late answering and again thanks for your contribution.

I've close reviewed your changes and write some comments. It should be fixed before I can merge your changes. Also some changes have to be made too:

• Use interactive rebase (git rebase -i HEAD~32) to correctly squash your changes to only 1-3 commits. (read more https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History). In short you need to squash your changes and force push it to your fork master, merge request will pick it up.
• You have to do not break backward compatibility with this changes. Python 2 also support named imports, am I right?
