RPCErrorMessage
case class RPCErrorMessage(code: Int, codeName: String, message: String, stackTrace: Option[Seq[GenericStackTraceElement]], cause: Option[Throwable], appErrorCode: Option[Int], metadata: Map[String, Any])
A model class for RPC error message body. This message will be embedded to HTTP response body or gRPC trailer.
We need this class to avoid directly serde RPCException classes with airframe-codec, so that we can properly propagate the exact stack trace to the client.
