Feedback

Original calucaltion:

64,000 ports per IP / <outbound ports per node> * <number of outbound IPs> = <maximum number of nodes in the cluster>.

Propose change:

The maximum number of nodes in the cluster = (sum of the maximum or fixed node counts across all agent pools) + (one buffer node for each agent pool)

To figure out ports/IPs: (64,000 ports per IP / <outbound ports per node>) * <number of outbound IPs> >= <maximum number of nodes in the cluster>
