1. e2e dra: collect and check GRPC calls …

   If kubelet plugin registration fails, it would be good to know more about the
   communication with kubelet. Capturing the GRPC calls and then checking that
   makes the failure messages more informative. Here's an example where a failure
   was triggered by temporarily modifying the check so that it didn't find the
   call:
   
     [FAILED] Timed out after 30.000s.
     Expected:
         <[]app.GRPCCall | len:2, cap:2>: [
             {
                 FullMethod: "/pluginregistration.Registration/GetInfo",
                 Request:
                     {},
                 Response:
                     endpoint: /var/lib/kubelet/plugins/test-driver/dra.sock

                 Err: nil,
             },
             {
                 FullMethod: "/pluginregistration.Registration/NotifyRegistrationStatus",
                 Request:
                     plugin_registered: true,
                 Response:
                     {},
                 Err: nil,
             },
         ]
     to contain successful NotifyRegistrationStatus call
