[Container Request]: VADR 1.7 slim (no models included)

### What tool are you looking for and why?

This is a reminder for myself.

Need to create a VADR docker image where no model files are included. This image will serve as the base image for other docker images that do come pre-packaged with models for various organisms.

See PR #1534 and comments within for more info.
