> The XceiverServerRatis#raftGids are accessed in the following places
> + XceiverServerRatis#isExist
> - CloseContainerCommandHandler#handle
> - CreatePipelineCommandHandler#handle
> - BlockDeletingService#isDeletionAllowed
> + XceiverServerRatis#notifyGroupRemove
> - ContainerStateMachine#notifyGroupRemove
> + XceiverServerRatis#notifyGroupAdd
> - ContainerStateMachine#initialize
> So there are at least 2 threads:
> - BlockDeletingService Thread
> - CommandHandlerThread
> so we need to make it thread-safe.
