Reduce docker image size with multi-stage builds

[felrock]

Are there any examples of adding a multi-state build to the Dockerfiles in this repo? For example what to copy from the nvidia jetpack base image and so on. Thankful for any input.

The l4t-ml container is a multi-stage build, because it copies the Python modules from the l4t-pytorch and l4t-tensorflow containers. However this is mostly a time-saver instead of space-saver. I think it would be difficult to further reduce image size without removing packages - which could be fine if you don't need them.
