DATACMNS-364 - Add generic support for customisable finders by respecting custom query annotations.

Introduced new meta-annotation "QueryAnnotation" to mark and identify store specific Query-Annotations. This enables us to handle finder methods annotated with such store specific annotations in a generic way. Adjusted DefaultRepositoryInformation.getQueryMethods to consider custom store specific query annotations.
