[bug#40195] [EXTERNAL]Re: [bug#40195] Add Docusign python API module as a package

[Leo Famulari]

Thanks for the revisions! I pushed as
b14c234c0d32216f8c2f6e6d1935c469a6b947c9 with a few more changes:

I made it fetch from PyPi instead of Git since they didn't actually tag
a 3.1.0 release. We'd rather take the thing that upstream definitely
says is "the release" in cases like that.

I made the variable name and package name consistent.

And I simplified the synopsis to hopefully improve searchability.
