CI down on chicken-and-egg patch unable to merge because of puppet-lint job

[Jiří Stránský]

We wanted to sync-merge two chicken-and-egg patches (puppet-tripleo + t-h-t).

The first one merged fine but the 2nd one hit a problem with puppet-lint job, and reverify failed too. We seem to hit the exact right few minute interval to make this happen...

Here's the one that merged:

Here's the one that didn't pass gate even though it passed check:

https://review.openstack.org/#/c/348816

All we need to do to fix this is to `reverify` the patch once puppet lint job is operational again. Reverting the 1st patch will not help because the revert wouldn't pass CI either if the lint job is really broken.

Note that the failure happened after Worfkflow+1 when jenkins did a lint check again and it failed with:
