Interceptors

[deepakrkris]

• Must be able to inject request/response interceptors for a Controller

     @intercept('request',  function(request, next) {
        logMessage(request, next);
     });
     @intercept('response', './scripts/error-handler');
     @intercept('request', './scripts/user-context');
     @api(def) 
     class OrderCancellationController {
     .....
     }

• interceptors will be invoked in the order of declaration for the controller
• interceptor scripts must export a function with a specific signature
• An interceptor can modify the request/response, headers and body

need a way to register the decorators for interceptors

I think this is conceptually similar to remoting hooks (beforeRemote, afterRemote, afterRemoteError) in LoopBack 3.x
