1.7.2 breaks upload to internal pypi repo backed by artifactory

[pbuckley]

We used to be able to twine upload -r pypi-local dist/* (pypi-local is an internal artifactory server, configured according to the artifactory manaul https://www.jfrog.com/confluence/display/RTF/PyPI+Repositories). Starting July 5th (the 1.7.2 release) it began to fail with the below error. Can you confirm that 1.7.x introduced this new SSL requirement for twine, or is there a fix/workaround we could use? Currently dropped back to twine 1.6.5 and that fixed us.

1. There is no 1.7.2 release.
2. This is not a new SSL requirement. We updated to a newer minimum version of requests that warns you when you're making an HTTPS requests without good OpenSSL support in your version of Python.
3. It looks like our pre-check to see if a package has already been uploaded (to support --skip-existing) is what's actually causing this to break.

#192 will probably fix this.

👍 thanks! (and sorry I typo'd 1.7.2, meant 1.7.1)

Fixed in afc9956.
