- make release images ALL based from centos:7
- keep eks images that are based from amazonlinux:2, but create strong alignment with release (centos7) images
- use multi-stage Dockerfile(s)
- have a single build-images script
- remove per image directories (which would only contain scripts that are copied into images)
- remove empty requirements.txt file for sidecar.py (the pip command, package and version are in the Dockerfile)
- don't copy docker into PROJECT_BINARY_DIR
