### Description

Currently, KubernetesPodOperator fetches logs using
```
             self.pod_manager.fetch_container_logs(
                    pod=self.pod,
                    container_name=self.BASE_CONTAINER_NAME,
                    follow=True,
                )
```
and so only shows log from the main container in a pod. It would be very useful/helpful to have the possibility to fetch logs for all the containers in a pod.


### Use case/motivation

Making the cause of failed KubernetesPodOperator tasks a lot more visible.
