Autoconfiguration: Add an option to specify which DataSource should be used.

[NicklasWallgren]

Currently, the DbSchedulerAutoConfiguration selects the primary DataSource bean by default, which may not always be the desired behavior.

Although it’s possible to override the default Scheduler bean, this approach can be somewhat cumbersome.

An alternative solution could be to either update the DbSchedulerCustomizer to include a datasource method or implement a custom DataSourceSupplier.

What are your thoughts on these approaches?
