Add Integration Tests asserting the configuration of PDX in the context of Spring Boot.

Adds 3 test cases covering:

* Auto-configuration of SDG's MappingPdxSerializer.
* Configuration of a custom, user-defined PdxSerializer applied by auto-configuration.
* Overriding PDX auto-configuration with a manually specified PDX configuration.
