DATACMNS-452 - Added some helper types to simplify the implementations in store modules.

Added AnnotatedTypeScanner to easily scan for annotated types within a set of base packages. Picks up interfaces by default which had to be customized when using ClassPathScanningCanidateComponentProvider.

Added DirectFieldAccessFallbackBeanWrapper that will use direct field access for beans in case no accessor method can be found. This allows to easily implement bean property values through accessors first but using the field directly if the accessors aren't available.

Introduced AnnotationDetectionMethodCallback to easily find methods equipped with a given annotation.
