Add access to an organization

[F0urchette]

Description

As a user
I want to the give access rights to an organization
So that I can use its repositories in my project
But I don't know if the Github API allows me to manipulate OAuth rights or even to delete an OAuth key and ask for access again afterwards

[F0urchette]

There may be a way to get the user to revoke the OAuth access token here

The solution mentioned here seems to be the most interesting, it is the one that we will set up here.
