Enable to disable default background process, or using custom background process instead of the default one?

Since the defualt RecurringJobScheduler didn't support expire date for recurring job, so I want to use [RecurringDateRangeJobScheduler](https://github.com/jcoutch/Hangfire.RecurringDateRange) instead.

Although it works, but the defualt RecurringJobScheduler is running also.

So I want a way to use the custom background process to instead of the default one.

Start by reading how the default RecurringJobScheduler is registered and started, then compare that integration with the linked RecurringDateRangeJobScheduler package. Define how users can disable or replace the default process, and verify that only the selected scheduler runs for recurring jobs.
