    Don't rely on overcloudrc

    We were reading overcloudrc for the openstack-endpoints validation.
    However, the name of tha file may differ if the deployment plan is
    called something else than "overcloud" and more importantly, the GUI
    deployments don't create the file on the undercloud at all.

    This updates the Ansible inventory to read the admin password and
    keystone url for the specified plan if available and the validation to
    use those values instead of relying on overcloudrc.
