SpringBoot DataSourceInitializationConfiguration should back off if datasource initialization is disabled

If an application has configured spring.datasource.initialization-mode=never we are still registering DataSourceInitializerInvoker and its post processor. It looks like ultimately they do nothing so we should probably not register this infrastructure at all.

Thanks for offering to help but datasource initialization is a tricky topic and there are a number of things we'd like to verify as part of the issue. I've assigned myself to make that more clear. Thanks for the offer in any case.

Ok, no problem.

This has been addressed in 2.5 as part of the revamping of DataSource initialization.
