In inventory/group_vars/repo_all.yml, internal_lb_vip_address needs to use ipwrap to handle IPv6

[Niklas Hagman]

In my work to make openstack-ansible work with IPv6, I have found that internal_lb_vip_address needs to be ipwrap:ed to support IPv6 addresses in the file openstack/openstack-ansible/tree/inventory/group_vars/repo_all.yml.

# The URL to retrieve the get-pip.py installation script locally
pip_upstream_url: "{{ repo_release_path | replace(internal_lb_vip_address, '127.0.0.1') }}/get-pip.py"

# The URL to the local PyPI reverse proxy
pip_default_index: "{{ openstack_repo_url | replace(internal_lb_vip_address, '127.0.0.1') }}/simple"

needs to be replaced with

# The URL to retrieve the get-pip.py installation script locally
pip_upstream_url: "{{ repo_release_path | replace(internal_lb_vip_address | ipwrap, '127.0.0.1') }}/get-pip.py"

# The URL to the local PyPI reverse proxy
pip_default_index: "{{ openstack_repo_url | replace(internal_lb_vip_address | ipwrap, '127.0.0.1') }}/simple"

Another suggestion is to use "localhost" instead of "127.0.0.1".
I do not see 127.0.0.1 being replaced soon with ::1 but I do think it is the right move to do early on and let the running linux distribution decide what localhost translates into.
