Review Comment:
I think the description should detail what the config is good for. Does it
affect artifact downloading?
It doesn't need to explain how configurations work, we have general docs for
that. So I would completely remove this part:
```
If configured in cluster level, headers will be applied to all jobs within
the cluster. This field can also be configured under
spec.job.flinkConfiguration for a specific session job within a session
cluster. If configured at session job level, it will override the cluster level
configuration.
```

Review Comment:
I think it's a bit confusing to call it `getSessionJobObserveConfig`. I
would prefer to call it simply `getSessionJobConfig`

The `!sessionJobFlinkConfiguration.isEmpty()` check is not necessary

We shouldn't add this extra field here, it's not an operator configuration
and it's also not used anywhere

Could we please add a simple test for this into the validator test?

Review Comment:
I am wondering for this particular case, would it make sense to merge the
HTTP headers instead of overwriting them if the base config also defined it?
