-Why the two differing ways to provide the same properties? We previously accepted a `-D` tooling option which resembled Java System Property declaration. In older versions of OpenAPI Generator, the option modified the SystemProperties collection directly and was truly a "system property". This option changed during the 4.x release in an effort to make OpenAPI Generator thread-safe and isolate its configuration via thread locals. We no longer mutate System Properties. In the 4.x release and earlier, specifying the tooling `-D` option with system properties intended for other tools like swagger-parser rather than passing them as true Java System Properties would lead to unexpected behavior for the user; if our tool set the system property _after_ invoking certain code, it would seem to the user like Java System Properties weren't working!
