@belimawr do you know if we need to backport something for the tests to pass? It's failing in TestLogIngestionFleetManaged/Monitoring_logs_are_shipped.

Yes, I need to get a couple backport PRs in 8.15, I should get them merged today, if CI is green.

The PRs I need to backport:

• [8.15](backport #5375 #5409 #5361) Fix flaky tests #5410, but it's failing on CI
• [Integration Test Framework] fix createTempDir and flaky tests #5409, this will fix the issue with the PR above, then it needs to be backported.

Because both PRs fix CI issues, I'm planning to consolidate them into a single backport PR. I'm still waiting for CI to run, so hopefully I'll get this done tomorrow.

aren't we getting into a chicken egg problem? One backport failing because it needs the other.
Isn't better to merge them all in a single PR? What do you think @belimawr and @rdner?
