> Currently we use a constant of 10 seconds as both the zookeeper session timeout and the local timeout. However, the timeout proposed by the client maybe rejected by ZK if it violates the server's (max)minSessionTimeout.
> We should read the negotiated timeout and set local timer to use a value smaller than that. e.g. half of it.
> This is to ensure that if the leading master is partitioned, it terminates asap when it's session is destined to expire.
