Fixed issues due to parent-boot-2 migration (migration to Spring-boot 2):

* Configured Hiberante 5 correctly
* Configured Git plugin correctly
* Changed hibernate methods to comply with new method naming conventions
* Removed and replaced deprecated properties
* Updated Actuator test to use new response structure
* Using random port in Mongo integration test, to avoid clashing with a potential instance using the mongo default port
