This allows quartz jobs to be automatically provisioned at startup. It has the advantage over the
builtin Spring Quartz support of optionally not overwriting any changes that are made. This is in a JAR as
there's no way to load resources from a component apart from having a class in there.
Although SchedulerManagerImpl can automatically provision jobs these have to be in the job scheduler and can't
be in other projects. So in the future this method is preferred.
