  /**
   * Sharing server is an independent gRPC and REST servers provided for all receiver modules. In default, this module
   * would not be activated unless the user active explicitly. It only delegates the core gRPC and REST servers.
   *
   * Once it is activated, provides separated servers, then all receivers use these to accept outside requests. Typical,
   * this is activated to avoid the ip, port and thread pool sharing between receiver and internal traffics. For security
   * consideration, receiver should open TLS and token check, and internal(remote module) traffic should base on trusted
   * network, no TLS and token check. Even some companies may require TLS internally, it still use different TLS keys. In
   * this specific case, we recommend users to consider use {@link org.apache.skywalking.oap.server.core.CoreModuleConfig.Role}.
