iptables: handle hosts in allowed groups not having an ipv6 address 
The modified section of the rules.v6 template looks at the groups in
the iptables_allowed_groups list and then allows access for each host
specified in that group.

Currently this extracts the 'public_v6' from the hostvars[host]
directly, but this fails if the host in question doesn't actually have
an ipv6 address.

Modify this so we check if the variable exists, and then reference it
via the hostvars dict.  Note that in gate testing, ipv6 may be empty
string (set from nodepool values), while it may not be a value at all
if it is left out of the production inventory.
"hostvars[host]['public_v6'] | default(False)" should catch both
cases.
