If, for any reason (e.g. server crash), a task is recorded as done in the database but the logs are still in the database instead of being in storage, they need to be collected.
The log_in_storage field is only set to true after the logs have been transfered to storage and can be relied upon to reflect which tasks have lingering logs.
A cron job collects lingering logs every day, 3000 at a time, sleeping one second between them. In normal circumstances there will be only a few of them, even on a large instance, and there is no need to collect them as quickly as possible.
When there are a lot of them for some reason, garbage collection must happen at a rate that is not too hard on storage I/O.

Fix#25451.
Bugfixes:
- When stopping the zombie or endless tasks, set `LogInStorage` to true
after transferring the file to storage. It was missing, it could write
to a nonexistent file in DBFS because `LogInStorage` was false.
- Always update `ActionTask.Updated` when there's a new state reported
by the runner, even if there's no change. This is to avoid the task
being judged as a zombie task.
Enhancement:
- Support `Stat()` for DBFS file.
- `WriteLogs` refuses to write if it could result in content holes.
