Comment 1 for bug 1690203

v3.Token will never be able to support re-authentication (you can use one token to get another, but the expiration date of the next token cannot exceed that of the original token, to prevent a malicious user that is able to get a token from being able to extend their access indefinitely). So simply returning the existing token from get_token without worrying about checking expiration and re-authentication should be a sufficient fix here.
