DATAMONGO-980 - Use meta annotations from commons for @Score.

We removed meta annotation `@Calculated` and replace its occurrence with `@ReadingProperty` from spring data commons. Additionally `MappingMongoConverter` makes use of `doWithWritingProperties` for selecting properties to be written into the `DBObject` saved in mongodb.
