* Fix up a few things related to min, start and gateway address

- the get address pools api was incorrectly only returning the min address, not the configured gateway
- the IP allocation code was always starting at min address, instead of starting at start address
- min address should be the min address in the range, not the configured start address.
- Added a basic unit test for the ipam api

To create a production zip and deploy to production:

  • ensure capistrano 2.15.5 is installed
