* I don't think the "use a single file for both" (what i set out to do in this
jira) is ever going to be viable.
* I've created SOLR-15335 which has a new approach for a common "body" that we
pre-pend (templated) "headers" onto thati think will server th best balance
between producing what we want, producing what docker-library requires,
minimizing duplication, and maximizng readability.

> 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.
