Bug Description
dhcp_relase does not work with IPv6, but IPv6 leases still should be released. Example:
1. Start VM in dhcpv6-statefull network, make it acquire IPv6 address.
2. Delete VM.
3. Start another VM in same network before lease expires.
There's a very high chance that same IPv6 address will be allocated for both these VMs (same address will be reused after first VM was delete). On DHCP agent hosts file would be changed, but lease file not, so dnsmasq will not give second VM address until lease expitres. Reducing lease time is not a good solution here...

DHCPv6 Stateful is not currently being tested, due to the fact that Cirros does not support it yet
