I found that multiple calls to delete_port can pile up on the _recycle_ip operation. This patch simplifies this operation. It reduces the _recycle_ip operation to a single row delete in the ip allocations table and doesn't touch the availability table. To acheive the recycling of ips in a pool, this code runs a more complex operation of rebuilding the availability table when it is exhausted. Only one API process will perform this more expensive operation and others waiting for allocation will immediately benefit. The amortized cost of this operation is much less than the cumulative cost of running the more expensive _recycle_ip operation for every port delete. IP allocation behaves a bit differently with this patch. Instead of giving out the first IP available in a pool, the entire pool will be allocated before wrapping around and recycling ip addresses that have been released. This is a desirable feature as it puts ip addresses in a sort of quarantine after they are released. It is easier to distinguish newly allocated ips from old ones.
