Let's say we deploy a web-app that has e.g. context path '/simple'.
Then we would need to configure the IsisConfiguration property 'isis.services.swagger.restfulBasePath' (default = '/restful') to '/simple/restful', in order for the swagger-ui to work properly.
We can instead implement o.a.i.c.m.services.SwaggerServiceDefault such that it automatically prefixes the swaggerBasePath with the app's context path (if present).
