Service Definition is not implemented

[aapris]

Open311 standard says that if a service object in services.json has "metadata":true the service definition should be available in URL https://[API endpoint]/services/[service_code].[format].

Example:
http://test311api.cityofchicago.org/open311/v2/services/4ffa4c69601827691b000018.json

However, current implementation returns HTTP 404 even when "metadata":true.

This is related to #14. Service metadata is currently not supported.
