Allow custom configuration via Options pattern

Is your feature request related to a problem? Please describe. “I’m always frustrated when” I cannot access IServiceProvider in the configure action of AddQuartz.

Describe the solution you’d like AddQuartz should have an overload like AddQuartz(this IServiceCollection serviceCollection, Action<IServiceProvider, IServiceCollectionQuartzConfigurator>? configure = null) similar to eg. AddContext.

Describe alternatives you’ve considered Alternatively Quartz could expose an options interface, and I could configure with eg. IConfigureOptions<QuartzOptions>. For example AddCors does this with CorsOptions. One can use IConfigureOptions<CorsOptions> to configure cors and access IServiceProvider.

As a workaround I can manually bootstrap the dependencies I’d like to access in AddQuartz.

Additional context My use cases are similar to Andrew Lock’s described in this blog post. Hope you find some inspiration there.

Many thanks!

EDIT: To be clear, this is a minor improvement on the configuration interface as feedback was requested.

@lahma Looks great for my needs, thanks!

So I’ve done changes required to achieve @kevinchalet 's proposed idea with PR https://github.com/quartznet/quartznet/pull/978 . Hopefully this is nor more in line with expectations from options pattern and allows to do the Configure.
