Close open Jira tickets flagged "top_flaky_test", if the test function is no longer flaky

• Go through all open Jira tickets, flagged with "top_flaky_test" on dev, 6.9, 6.8, 6.5
• Check whether the test function is still flaky (by inspecting relevant Grafana dashboards or other appropriate means)

=> If the test is still flaky, add a respective comment to document that it is flaky and unfixed.

=> If the test isn't flaky anymore, add a comment (if possible to) document when the flakiness has stopped.

• if it's blacklisted, push an unblacklisting patch that closes the ticket.
• If it isn't blacklisted, close the ticket.

Let's start with the oldest tests affecting dev.
As for missing data in week 27, it can be assumed that a test that hasn't been flaky for 4 weeks before week 27 hasn't become flaky again in week 27.
