Describe a service:

quarkus grpc describe localhost:8080 helloworld.Greeter

{
  "name": "helloworld.proto",
  "package": "helloworld",
  "dependency": ["google/protobuf/empty.proto"],
  "messageType": [{
    "name": "HelloRequest",
    "field": [{
      "name": "name",
      "number": 1,
      "label": "LABEL_OPTIONAL",
      "type": "TYPE_STRING"
    }]
  }, {
    "name": "HelloReply",
    "field": [{
      "name": "message",
      "number": 1,
      "label": "LABEL_OPTIONAL",
      "type": "TYPE_STRING"
    }]
  }],
  "service": [{
    "name": "Greeter",
    "method": [{
      "name": "SayHello",
      "inputType": ".helloworld.HelloRequest",
      "outputType": ".helloworld.HelloReply",
      "options": {
      }
    }, {
      "name": "SayJo",
      "inputType": ".google.protobuf.Empty",
      "outputType": ".helloworld.HelloReply",
      "options": {
      }
    }, {

      "inputType": ".helloworld.HelloRequest",
      "outputType": ".helloworld.HelloReply",
      "options": {
      }
    }]
  }],
  "options": {
    "javaPackage": "examples",
    "javaOuterClassname": "HelloWorldProto",
    "javaMultipleFiles": true,
    "objcClassPrefix": "HLW"
  },
  "syntax": "proto3"
}
{
  "name": "google/protobuf/empty.proto",
  "package": "google.protobuf",
  "messageType": [{
