    Fixup the memcached servers string in nova.conf for v6

    As discussed at https://bugzilla.redhat.com/show_bug.cgi?id=1299265
    when providing a list of IPv6 addresses as the memcache_node_ips
    the resulting nova.conf entry can't be parsed properly.

    This adds a memcache_node_ips_v6 which has the required format like
    inet6:[ADDR1],inet6:[ADDR2],inet6:[ADDR3]
