Do we want to have docker_image as a default tag?
We wanted to replace it with the combo image_name / image_tag (same cardinality but much more flexible), and kept docker_image just for compatibility (as said in the config file).
Did we change our mind?

I think it makes sense to keep it so we don't break everything (dashboards monitors) and as you said it's the same cardinality as image_name / image_tag so it's not creating more contexts, i think it's a good compromise.

Since it seems include is meaningless without exclude, should we show a warning for the case instance.get('include') and not instance.get('exclude')? I can see that being a common mistake

We should remove it since we auto-detect the path. If a new platform with a different mount point arises we'll add its path in dockerutil.py so that it's supported out of the box anyway.

The point about this option was to allow users on a new platform/with a new cgroup pattern to configure the Agent, without waiting for a new Agent release.
That's pretty minor, maybe not worth spending the time to add this feature,
This is a new version of the docker check, it's called docker_daemon (name can be changed).
The previous check "docker" is now deprecated and won't receive further support.
In terms of features, this adds:
- Support for TLS connections to the daemon
- New metrics:
- Network metrics
- Memory limits
- Container size (rootfs)
- Image size
- Support for labels (convert them into tags). Off by default, uses a list of labels that should be converted.
- Support for ECS tags: task name and task version
Backward incompatible changes:
- docker.disk.size metric is renamed to docker.container.size_rw
- Old optional metrics: https://github.com/DataDog/dd-agent/blob/5.4.x/checks.d/docker.py#L29-L38 Are not collected anymore
- Old old tags are not supported anymore (e.g. `name` instead of container_name)

It looks like the default in the code is still True.
