Description of problem: https://github.com/openshift/installer/blob/master/docs/user/openstack/install_upi.md Lists OpenStack Glance as an option to help inject the bootstrap ignition file. However, some openstack installation run TLS with self-signed certs. This will prevent the CoreOS bootstrap machine to bootstrap. Without knowing this the person deploying will wait forever for the api to come up. We should at least list this as remark. Use OpenStack Glance making sure the CoreOS can use it via HTTP, or via HTTPS if it has a trusted CA. An untrusted CA (self signed) should either injected in the ignition file or added to the CoreOS image via other means.
