This branch splits out the IPv6 address generation into pluggable backends. A new flag named ipv6_backend specifies which backend to use.

The existing code (which is also the default) is now available as nova.ipv6.rfc2462 while a new backend available as nova.ipv6.account_identifier implements an algorithm that includes an account identifier as part of the address.
