[bug#56404] [PATCH 0/2] gnu: Add python-msal and oauth2ms.

[John Kehayias]

Hello Guix,

Here are two straight forward patches to add python-msal and oauth2ms. Short 
commentary:

1. python-msal: a package for Microsoft authentication tokens. Tests were 
disabled because most/all needed network access, and could only disable some of 
these tests with an environment variable. I did use the GitHub source since it 
includes tests, in case this can be better worked around in the future, or if 
using the source directly.

2. oauth2ms: a python script to use msal in order to have usable tokens, like 
needing oauth2 tokens for getting/sending mail with multi-factor authentication 
required email services. I copied the readme and steps.org which have 
documentation for setting this up to the appropriate doc folder. There is no 
release or version tag and the script needed to be wrapped.

As a final note, I've used this to send mail through my university email server 
that uses Microsoft Office 365 with multi-factor authentication (so you can't 
use your password or an app password). oauth2ms provides instructions for doing 
this in emacs, which I used for mu4e. And if you can't create the needed keys 
in Azure (as I couldn't) you can use Thunderbird's 
https://hg.mozilla.org/comm-central/file/tip/mailnews/base/src/OAuth2Providers.jsm#l127
 along with your providers "tenet id" which I could find by logging on to Azure 
even without permissions to create an app.

Hope someone else finds this useful!
