Feature request: Pruning of layers of specific image

When using Docker for a large amount of projects on a personal machine, and frequently rebuilding large containers, one may find themselves requiring to prune cached layers from previous builds to free up disk space.

The only way to do this, is by pruning all dangling layers, using docker builder prune. This is inconvenient, as one will lose cached layers from all the containers of all projects on the machine.

Instead, it would be much nicer to have a command where one could prune the layers of a specific image, or alternatively, have a flag for the docker rmi or docker image rm command, that after removal of the image, also prunes all of its layers that are now dangling.

This way, one could have a build script where an image is rebuilt, and after rebuilding, remove the old image and its now dangling layers. This way, disk space is optimally preserved for the image in question, without affecting other projects.

Start by investigating the existing docker builder prune, docker rmi, and docker image rm entry points and how they identify cached layers. Define the intended command or flag behavior, including which layers are safe to remove and how other projects' caches are protected; done requires documented behavior and tests for image-specific pruning.
