`WARN ... found future (image|delta) layer` are not actionable log lines. They don't need to be warnings. `info!` is enough. This also fixes some known but not tracked flakyness in [`test_remote_timeline_client_calls_started_metric`][evidence]. [evidence]: https://neon-github-public-dev.s3.amazonaws.com/reports/pr-4829/5683495367/index.html#/testresult/34fe79e24729618b Closes #3369. Closes #4473.
