[CANARY] Disable test retries

[apostasie]

IMHO we cannot keep on hiding problems by "retrying tests" until it works.
This is a doomed approach.

I perfectly understand how painful it is to go and debug these flakyness / concurrency issues, and that it is much easier to ignore the problem - but we have to solve these - they are definitely indicative of deep quality issues and the only way to do so is to make it as obvious as possible instead of hiding it under the retry-carpet.

This is a canary PR that will very likely keep failing for some time - until we fix ALL these issues.

I will rebase it against main daily, and eventually we should get it green and stable.

Finally note that this canary is usually AHEAD of main - using commits from pending PRs fixing flakyness

Of course, please do not restart any of these manually.
It should be green on the first try immediately after push.

Green again, but #3225 is still a clear issue before we can consider merging this.

The logs one is perplexing, but far from being the only log problem in CI. We should really have a look at logs overall.

The IPFS one is also happening often - use of closed network connection may suggest low quality code / failure to handle errors? IPFS overall has been very flaky so same here, a serious rewrite might be in order.

Closing in favor of #3305
