fix jaegerremote parser to use jsonpb unmarshaler

4

Failed to parse sampling strategy response: json: cannot unmarshal string into Go struct field SamplingStrategyResponse.strategyType of type api_v2.SamplingStrategyType: ```json {"strategyType":"PROBABILISTIC","probabilisticSampling":{"samplingRate":1},"operationSampling":{"defaultSamplingProbability":1,"defaultLowerBoundTracesPerSecond":0,"perOperationStrategies":[{"operation":"/health","probabilisticSampling":{"samplingRate":0}},{"operation":"/metrics","probabilisticSampling":{"samplingRate":0}}}],"defaultUpperBoundTracesPerSecond":0}} ```

middleware: middleware registry & selector config

### Feature-request ### Proposal middleware registry，类似 [gateway registry](https://github.com/go-kratos/gateway/blob/main/middleware/registry.go)，可以通过名称进行注册管理； yaml 配置，并且通过 对应名称的 middleware，这个 yaml 配置将会放到 proto 相同目录，通过工具生成配置注册； selector，通过 operation 进行匹配选择对应的 middleware。 例子： ```yaml type: google.api.Service config_version: 3 name: library-example.googleapis.com title: Example...

### Feature-request ### Proposal 通过 `google/api/client.proto` 进行 default_host 并使用 protoc-gen-kratos 生成 Client，例如： ```proto import "google/api/client.proto"; // The hostname for this service. // This should be specified with no prefix or...

Incompatible behavior changes: - v2.3.1 Registry Endpoint: - #2076 #2071 - v2.3.0 WithLogger Option: - https://github.com/go-kratos/kratos/pull/2061 - `config.WithLogger/http.WithLogger/grpc.WithLogger` use `log.Info()` instead.

[HTTP2/Trailers] 代理缺少trailers返回

 通过gRPC客户端请求HTTP2，Response Trailers丢失： rpc error: code = Internal desc = server closed the stream without sending trailers

content-type: - application/x-protobuf - application/x-google-protobuf - application/grpc - application/grpc+json 如果是gRPC需要去除body前面【5bytes】 = 【1 gzip-flag + 4 length】（因为streaming需要body header实现 https://github.com/uw-labs/bloomrpc  https://www.charlesproxy.com/documentation/using-charles/protocol-buffers/ https://docs.proxyman.io/advanced-features/protobuf 推荐个很不错的UI参考：https://proxyman.io/
