Introduce messages service/code-generation

Makes use of JSON files containing string messages which can later be accessed from within the CLI. A dev command (dev-generate-messages) is introduced for ease of use and autocompletion.
There is a default json message file with is loaded by default however each client may provide their own json file and thus override keys, extend and so on.
Includes a bit of refactoring concerning swagger code generation - extracting/moving common interfaces/implementation classes to common.
