Implement the tests for the HIGH priority scenarios of definitions in it.info.magnolia.functionaltests.DefinitionsFunctionalTests.

One scenario - Definitions contain no MAJOR or SEVERE problem -  is already implemented.

See acceptance criteria list for the scenarios which still need implementation.

Developer notes

Use LightModulesSupport/LightModule to bootstrap complete light-modules

• one for the valid definitions
• one for the invalid definitions

Possible assertions

• URI mappings (1 concrete case, easiest to verify)
• definitions endpoint
• definitions endpoint + logs
• definitions app
