tripleo-commong - get_undercloud_registry() does not support IPv6

[Harald Jensås]

https://opendev.org/openstack/tripleo-common/src/branch/master/tripleo_common/image/image_uploader.py#L96

The code only look for AF_INET address, and not for a AF_INET6 address.
On an undercloud with IPv6 address on the br-ctlplane interface the code defaults to localhost wich causes "Image prepare failed: 404 Client Error: Not Found for url: http://localhost:8787/v2/" in /var/log/tripleo-container-image-prepare.log.

    Image Uploader - get_undercloud_registry IPv6

    Adds support for IPv6 undercloud in the image uploader.
    The get_undercloud_registry will look for an IPv4 address
    first, then look for an IPv6 address.

    If the address is an IPv6 address brackets are added.
