Apache Flink

Hi
Completed jobs are staying on the Flink dashboard, and not getting cleaned.

I'm using this configuration:
`config.setLong("jobstore.expiration-time", 60L);`
`config.setInteger("jobstore.max-capacity", 2);`

What am I missing?

Always indicate your flink version. I am going to assume its above 1.14 so to affect this should be using
```config.setLong("jobmanager.archive.retention-time", 60 * 1000L); // 60 seconds```

and
```config.setInteger("jobmanager.archive.max-history-size", 2); // keeps at most 2 jobs in the archive```
adjusted for your requirements.
