GitHub outage using GitHub OAuth causes servers to be logged-out

[choldgraf]

For hubs running GitHub OAuth:

There was a GitHub API outage yesterday, which made servers of running users fail due to refresh token failing.
From a user's perspective, it looked like this:

• They logged in
• Started doing stuff in JupyterLab
• All of a sudden, clicking things became unresponse. The page didn't change, just no more interactivity at all on the page.
• Refreshing the page took you back to the login page.
• Logging back in worked for a time, but broke in the same way a few minutes later

What's going on?

From @yuvipanda :

• I'd imagine that refresh token refresh errors should get logged but otherwise ignored

The solution will be slightly more complicated because the refresh can also be used to check a user is still authorised.
