Michele Baldessari 6227484b60 IPv6 VIP addresses need to be /128
We currently hardcode /64 as our VIP addresses when using IPv6.
The problem with this is that some server code might bind to that
IP as a source address when doing inter-cluster communication
(rabbitmq/galera for example). So when the VIP moves there will
be effectively a network outage between the nodes, which should not
happen.

Likely this was hardcoded to /64 because the RA IPaddr2 needs a nic
parameter when /128 is specified. This is due to:
https://bugzilla.redhat.com/show_bug.cgi?id=1445628

We also make sure we use the ipv6_addrlabel option set to 99 so that
they will never be used as source ip addresses.
