Handle Dispatch Errors

[tmackenzie]

Dispatch Errors that occur in engine

• When a ask's url is not found.
• When a ask has a invalid content-type
• 404, 415, ...

Given a request with the header Content-Type: application/json When the url is matched and it expects Content-Type: application/json; charset=utf-8 Then add the header X-Reasons which is a unsecure jwt with the payload

[
  {
    "k": "Content-Type",
    "v": "application/json",
    "src": "hdr", 
    "exp": ["application/json; charset=utf-8"], 
    "msg": ""
  },
]

And set the status code to 415 And dispatch the request to a configured Unsupported Media Type Route.
