Description

We have had the need to specify system properties in the Docker container multiple times over the last year (Log4J vulnerability & JDK17 bugs). Fixing this would be much easier if we could rely on a envVar that we know isn't used by users, so we could pass this information straight to bin/solr.

Since the docker image and solr are released together, this is unnecessary for fixing bugs in newer versions. It is merely creating an easy vector to fix existing docker images, where we cannot update the bin/solr they are using.
