Hi, The telemetry integration test for oslo.messaging has started failing on the stable/queens branch [0]. A quick review of the logs points to a change in heat-tempest-plugin that is incompatible with the version of gabbi from queens upper constraints (1.40.0) [1][2]. The job definition [3] includes required-projects that do not have stable/queens branches - including heat-tempest-plugin. My question - how do I prevent this job from breaking when these unbranched projects introduce changes that are incompatible with upper-constrants for a particular branch? I've tried to use override-checkout in the job definition, but that seems a bit hacky in this case since the tagged versions don't appear to work and I've resorted to a hardcoded ref [4]. Advice appreciated, thanks!
