undercloud_public_host doesn't work with IPv6

[Bob Fournier]

When trying to set public endpoints to serve over IPv6, stackrc creation fails due to missing logic for parsing IPv6 address for OS_AUTH_URL

Steps to Reproduce:
1. Add undercloud_public_host = <IPv6 address>
2. run openstack undercloud install

Actual results:
