Make sure leases are maintained until release

Dnsmasq asks nova-dhcpbridge for existing leases on reboot, but
we don't return addresses that have been deallocated but not yet
released. This modifies nova to return leased but not allocated
addresses. It also delays removing the vif until we disassociate
the ip so we still have access to the mac address.
