ComponentFinder - Support for multiple packages to scan (multi-module builds)

[engrun]

Hi

Field/parameter "packageToScan" is now a String value, limiting packages to scan to one single package. As I do not want to scan the entire codebase, it would be convenient to be able to list multiple sub-packages to scan.

It seems like a quick fix in AbstractReflectionsComponentFinderStrategy

.filterInputsBy(new FilterBuilder().includePackage(componentFinder.getPackageToScan()))

the includePackage method in the reflections API takes a vararg of Strings, making it possible to easily refactor ComponentFinder to accept a list/array of packages to scan.

essentially changing this line to

.filterInputsBy(new FilterBuilder().includePackage(componentFinder.getPackagesToScan()))

that is, changing getPackageToScan to getPackagesToScan

This is also very relevant for multi-module builds.
E.g. when controllers depend upon services/repositories from other maven-modules.
