1.Forcefully shutting down one of the nodes running a statefulset pod, and then force deleting the pod  

I was able to get the new Pod created by manually editing the IPPool and removing the allocation in question from the spec. 
I also deleted the OverlappingRangeIPReservation related to the allocation. This allowed the IP to be issued to the new Pod.
