[Bug 1427022] [NEW] not releasing IP address when deleting VM, port, LB VIP
Public bug reported:
I am testing with Juno 2014.2.1 release.
When I delete neutron port, VM, or LB VIP, neutron.ipavailabilityranges table was not updated as expected.
(I mean subnet IPs are not released to be used again.)
##case 1. deleting neutron port
1-1 create network/subnet
