Keep or map to internal input attributes and query param names #95
Description
Adding openrouteservice to a graph i came across the following problem:
the api uses attribute and query param names like boundary.country, alternative_routes and boundary.rect.min_lon. On introspection and add command the names are transformed to camelCase i.e. boundaryCountry, alternativeRoutes, boundaryRectMinLon. As a result of this all keys including . or _ will be ignored or cause errors as the camelCased keys match none of the attribute / query params expect by the api.
