[openssl-project] Milestones and the 1.1.1 release

[Salz, Rich]

Thanks for finishing this off.
    
    https://github.com/openssl/openssl/issues?q=is%3Aopen+is%3Aissue+milestone%3A1.1.1

Are 6512 and 6396 the same, and closed because we made things more secure?

Is 6342 a python bug, they'll need to upgrade?

Is 6228 a foolscap issue?

I think we can close 6221 soon.

I will make a PR for 5037.
