This change relaxes the constraint that all subnets of the same address family on a network must be allocated from the same subnet pool. It allows subnets that share the same address scope to co-exist on a network. If there is no address scope involved the subnet pool / network affinity constraints continue to enforced as done previously. Change-Id: I33bd17c723b3e8d409415bda008440f8ed9cfa68 Closes: 1830240 Implements: subnets-different-pools-same-net
