I agree all those comments cause way to much noise. The most important
bit of the comment is the link that takes you to the CI logs so, it
may be probably enough to just have 1 link that will take someone to
the builds of the 3rd party CI for that specific change.
Along the lines of what you just proposed, what if each 3rd Party CI
username in the review's list just links to this "builds-list"
resources that a developer can go to to check the logs. Would that be
too much of a hack for gerrit?
I'd like to avoid us to create yet-another-monitoring-resource that
we'll have to go to in order to figure out what's going on.
FWIW, the above could also be done for our Jenkins.
Overall, +1 for the email and idea.
