Context:
Why don't we have a helper class, similar to the authorization client class, to create/deploy/run process/decision definitions? Right now, we have several abstract classes that start to copy the same code again, e.g. AbstractProcessDefinitionIT <-> AbstractFilterIT. Often one of the abstract class hierarchy doesn't fit and then we duplicate the code again in the other IT class.

AT:

• the code from the abstract IT classes (e.g. AbstractDefinitionIT) classes is moved to its own class similar to how it's done for the AuthorizationClient
• all engine clients are renamed to make it clear that they are being used for the engine communication, e.g. AuthorizationEngineClient
