Code review comment for lp:~mardy/account-plugins/mcloud-plugin-lp1587282

Upstream review was faster than expected. I've put the OAuth plugin in silo 59, the CI ticket is this one:
https://requests.ci-train.ubuntu.com/#/ticket/1497

If you don't have objections, I will also take this branch and put it in the same silo, so that it will be easier to test.
