Support for environment Variables in quartz.properties and/or job.xml's

[CxVercility]

Hi there,
I was wondering if it was possible to add support for environment variables in said files. (i havent found a way to do so, if there actually is one please enlighten me, the @ syntax seems to only work for variables of the properties files itself)

The specific use case for me is that I need to specify URL Targets and cron-expressions according to the system my scheduler is running on.

My current solution is to dynamically set the xml' fileName by overriding XMLSchedulingDataProcessorPlugin.initialize

public void initialize(String name, Scheduler scheduler, ClassLoadHelper schedulerFactoryClassLoadHelper) throws SchedulerException {
        String stage = System.getenv("ENV");
        this.setFileNames(stage + ".xml");
        super.initialize(name, scheduler, schedulerFactoryClassLoadHelper);
    }

This however still means that I need to provide 4 XML's which is kinda whack and also prevents me from maintaining these in the helm chart of my image.

I'd be happy to provide the code changes in a PR myself, if i can get confirmation that it would be accepted.

Seems reasonable to support.

Why not loading the cron-expressions, job group, name, etc directly from the database?. This is how I currently do it
