There was a problem hiding this comment.
When WARM_IP_TARGET is set, try to allocate that many IPs on the current ENI before allocating a new ENI.
As discussed offline, the problem is at low values of WARM_IP_TARGET, scaling up becomes excruciatingly slow. Perhaps we can try to allocate the full ENI, but if that fails, we can attempt to allocate using progressively smaller step sizes.

If that fails, try to just add 1 IP to the ENI
