### What do you see as an issue?

The `--state` CLI flag on `airflow dags list-jobs` does not tell the user what arguments it can take.

https://github.com/apache/airflow/blob/1bd538be8c5b134643a6c5eddd06f70e6f0db2e7/airflow/cli/cli_config.py#L280

It probably needs some keyword args similar to the following:

```python
 metavar="(table, json, yaml, plain)",
 choices=("table", "json", "yaml", "plain"),
```

### Solving the problem

The problem can be solved by adding those keyword arguments so that the user gets a suggestion for what state arguments can be passed in.

### Anything else

Any suggestions on what can be a valid state would be much appreciated. Otherwise, I'll find some time to read through the code and/or docs and figure it out.
