Description

This issue tracks PoC work experimenting with the idea of the following workflow:

For Users:

• a Dockerfile (or Dockerfile.local) in our git repo that can be used (directly or via gradle) to build docker images directly from a local solr.tgz (in the docker build context)

For Release Manager:

• The exact same Dockerfile serves as a "template" that gradle tasks use to generate a build/Dockerfile.official via some very simple substitutions to fill in ARG defaults based on the "official" solr-VERSION.tgz for this release
• This Dockerfile.official can then be committed to the docker-solr github repo (or some similar new 9.x+ repo) and can be build with a a completely empty build context – in which it downloads (and validates) the official solr-VERSION.tgz (based on the ARG values that were filled in during the release)
• Automated tests can help us "validate" that the generated Dockerfile.official will work prior to officially publishing release artifacts, by using a "mock" download server to host the local solr-VERSION.tgz file

The driving goal being that the Dockerfile used for official _/solr builds should be as close as possible to identical to the Dockerfile used for "local" builds by users – given the constraints put on us by the docker-library team.
