Validate interoperability with Kotlin's inline classes. #822

Inline classes won't work without a bit of massaging the parameter mapper during querying, reasons for that being: FasterXML/jackson-module-kotlin#199 |

Kotlin provides so called „Inline classes“ (https://kotlinlang.org/docs/reference/inline-classes.html), wrapping standard types into a dedicated type. This makes them a nice fit for IDs etc. The object mapping process works ootb, the parameter mapping needs some extra work: One has to provide custom serializers for all data classes being used (see `IdTypes`). Those serializers can be registered with a dedicated `SimpleModule`. This module needs to be added to the `ObjectMapper` instance used by OGM to convert parameters: ``` ObjectMapperFactory.objectMapper() .registerModule(KotlinModule()) .registerModule(IdTypesModule()) ``` The kotlin jackson module may detect them at some point in the future itself (See FasterXML/jackson-module-kotlin#199), but until than that work is necessary. This closes #822.
