Fix retry_enabled=False config flag to correctly disable SDK retry logic

[asqui]

This is needed because the retry logic in SDK doesn't work properly :-(
(see #21)

Thanks for the PR. Doing this does disable the retries, but then it doesn't retry at all, not even when it's enabled.
We have fixed the problem by implementing a custom callback function in #29

Hmm, that's surprising. I thought tested this and saw it correctly constructing a binary-tree of retry_any and retry_all objects.

If you think there's a bug in tenacity, it's worth submitting a bug report and/or PR at https://github.com/jd/tenacity -- I submitted a PR to this project last week and it got approved, merged, tested, and a new version released to PyPI inside of 90 minutes!

Closing this issue since it looks like you've worked around this another way.
