Use latest esp docker image with tag 1

[qiwzhang]

Otherwise, many users still using very old ESP image 1.16.0

Tag "1" is always points to the latest ESP image

[gguuss]

Pointing to the latest version makes sense.

What's the easiest way to test this? As far as I can tell, it's not working on Cloud Run, I'm seeing the following error in stackdriver logging:

Also, if this is a Java container it probably should not be committed to the python repo.

It seems that you were seeing the wrong error log. Here we only have some kube deployment yaml files. We don't have anything related to Java.

The only way to test it is to follow this doc. That doc uses this deployment yaml file.

LGTM as it will match the other service.
