ceph-mon: fix support for ipv6 on containerized mons

The fact ['ansible_$interface']['ipv4'] is a dictionary where
['ansible_$interface']['ipv6'] is a list. If we use
ansible_default_ipv6|ipv4 is is always a dictionary which allows us to
get the ipv6 and ipv4 address without adding more complexity to the
template.
