> I assume that the goal of this PR is to make the set of
core.hostname_callable=airflow.utils.net.get_host_ip_address not needed
(correct me if I'm wrong).
Partially yes. In order to make the calls work through the service we would
need to make a new method that strips the pod name from the FQDN returned by
`airflow.utils.net.getfqdn`, e.g.
```python
def get_host_service_name():
"""Service-aware hostname callable.
https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/#a-aaaa-records-1
"""
from airflow.utils.net import getfqdn
fqdn = getfqdn()
return ".".join(fqdn.split(".")[1:])
```
Without the subdomain this method does not work, as the pod's FQDN will only
return the pod name without the subdomain.
