Full credits to @alles-klar for the original PR #592.
This PR adds the option of configuring DVWA via environment variables. This allows users to change the configuration without rebuilding the Docker image and is particularly useful in a Docker or Kubernetes deployment.
I believe this PR was incorrectly reverted in #605 and was not the cause of #604. The only issue in the original PR came from a mismatch between the environment variable name in config/config.inc.php.dist and in the README.md. The database server variable was changed from DB_SERVER to DVWA_DB_SERVER, which caused some confusion. I've kept the original name of the variable in this PR to avoid any breaking change.
