Hello.

Kubernetes generates a unique pod name.
https://github.com/apache/airflow/blob/736a62f824d9062b52983633528e58c445d8cc56/airflow/kubernetes/pod_generator.py#L434-L458
It would be great if the pod name was available in Airflow after completing the task, so that, for example, we could use it to add [extra links](http://airflow.apache.org/docs/apache-airflow/stable/howto/define_extra_link.html) or use it as an argument in downstream tasks. To do this, we should save this name in XCOM table.

The operator for BigQuery works in a similar way.

Thanks to this, we have links to the BigQuery console.
