This change dynamically adjusts the maximum number of leases based on the size of the subnets associated with a network. The upper bound is limited by a configurable option to keep the max reasonable and prevent denial of service. Closes bug: 1225200 Change-Id: I75c3907bcf45cd991eadf5dd8c8ad7f1eaab3c85
