> The counter in ConnectionLimitUpstreamHandler and ConnectionPerIpLimitUpstreamHandler will decrease one more than expected when the connection reaches limit, therefore the handler can not really limit connection numbers.
> Say, if the limit is set to 2, connections will go like 0 -> 1 -> 2 -> refused -> 3 -> refused -> 4.
> And the total connection limit counter is offseted by 1.
