    @mxm , Thanks for your review. And I change the ResourceManagerHATest to use a mocked
RpcService instead of TestingSerialRpcService.

> 1. When a resourceManager is started, it starts the leadership election service first
and take part in contending for leadership
> 2. Every resourceManager contains a ResourceManagerLeaderContender, when it is granted
leadership, it will start SlotManager and other main components. when it is revoked leadership,
it will stop all its components and clear everything.
