Generate org.springframework.boot.autoconfigure.AutoConfiguration.imports file automatically

[rubasace]

This one isn't a big issue anyway but I feel like @AutoConfiguration annotation should be enough to indicate the intention of the developer to create an autoconfiguration that should be automatically registered.

Personally, I feel META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports might be redundant, though I might be missing some use cases the team has previously thought of. Even if the idea is for this not to happen automatically for some "user-protection" reasons, I believe it would be nice to offer a parameter on the annotation to opt-in. Something like register(boolean register) that can default to false.

Thanks for raising this @rubasace. We've been thinking about extending our annotation processor, or create a dedicated one that would create this file automatically.
