logx support global fields?

logx能否支持一下全局添加field功能，或默认加一个serviceName，收集日志想根据服务分索引很不方便

add a middleware, that use ContextWithFields to inject it in ctx.

You can use middleware:

server.Use(func(next http.HandlerFunc) http.HandlerFunc {
		return func(w http.ResponseWriter, r *http.Request) {
			serviceNameField := logx.LogField{
				Key:   "serviceName",
				Value: "xxx",
			}
                         otherField := logx.LogField{
				Key:   "other",
				Value: xxx",
			}
                        // ...

			ctx = logx.WithFields(ctx, serviceNameField, otherField)
			next(w, r.WithContext(ctx))
		}
	})

I want it, too. Middleware is not convenient.
