@jaristiz I can see that you closed v7 backport PR. Can you please reopen it?

@jaristiz I can see that you closed v7 backport PR. Can you please reopen it?

That branch requires way more work as one of the grpc components changed its interface, that's the reason why I closed it, I could reopen it but manual work will need to be done in order to bump this dependency and our immediate urgency was to get v8 done, I will be doing that once we get this one approved.

@a-b this pipeline has been shown inconsistent results on the reruns for the pipelines, which for me, from the outside look like fakes, is there something I can do from my side to get it green?

@a-b is there something we can do to get this PR merged? We still need this bump to fix the CVEs in our smoke tests release.
