The recent [refactoring of the celery Worker process](https://github.com/apache/airflow/commit/02ce45cafec22a0a80257b2144d99ec8bb41c961) dropped the use of `celery.bin.worker.Worker()`, and switched to using the `celery.app.worker.Worker()` class more directly.

Unfortunately, it was the task of the former to format the [Celery hostname patterns](https://docs.celeryproject.org/en/latest/reference/cli.html?highlight=hostname#cmdoption-celery-worker-n).

Unfortunately this refactoring dropped support for hostname patterns (`%h`, `%n`, etc.). Can we re-introduce these? All that is needed is a few `celery.utils.nodenames` calls:

```python
from celery.utils.nodenames import default_nodename, host_format

        # ...
        'hostname': host_format(default_nodename(args.celery_hostname)),
```
