Docker image of xcom_sidecar is not configurable

[raycarter]

Description

The iamge of xcom_sidecar is not cunfigurable (code: xcom_sidecar.py#36). In our situation we can not access the "alpine" image from the docker image registry. Then the pod will not be started because the pulling of image failed.

Therefore it would be very nice that the image of xcom_sidecar is configurable so that we can pass an image hosted by our registry.

I see there was a merged PR about this feature #26766. But the changes was deleted in the commit a1f5a54.

Could you please review it and add this feature again? Thanks!

Use case/motivation

Usecase:

Use KubernetesPodOperator with do_xcom_push=True in an environment which can not access docker image registry.

Thanks for filing this request. I can understand for private hosted environment the access to public docker registry might be limited. Had been myself in the same situation.
