Ubuntu 20.04 prohibits TLSv1 by default about libcloud

[Kami]

Which Libcloud version you are using?

We switch to the requests library multiple years ago and I believe this constant is actually unused since then (we just left it there for backward compatibility reasons, but it's not actually being used anywhere).

I will dig in to confirm that's indeed the case. And in case it is, I will update the code + docs to remove reference to that constant.

@jklint I confirmed that this constant is indeed unused - https://github.com/search?q=repo%3Aapache%2Flibcloud++SSL_VERSION&type=code and this has been the case since 2016 / 2017 when we switched to the requests library for making HTTP(s) requests.

Rightfully so, since using anything < TLS 1.2 is considered unsafe and not a good practice in this day and age.

It would still be good to know with which libcloud version you encountered this error since changing that constant would only work and have an affect in case very old version of libcloud is used.

I also went ahead and removed that dead and unused code to prevent confusion in the future - 56674f4.

Closed this as a non issue in the recent Libcloud versions (only affects extremely old releases).
