    Enable Horizon to consume a Keystone v3 API endpoint

    This patch enables Horizon to consume a Keystone v3 API endpoint.

    This patch also introduces two variables to allow the endpoint to be
    specified independently if required:
     - horizon_keystone_host: this defaults to the internal LB IP address
     - horizon_keystone_endpoint: this defaults to the internal Keystone
       endpoint

    This patch also does the following:
     - properly consumes the horizon_ssl_no_verify role setting;
     - includes a little comment cleanup which does nothing but clutter
       the local_settings configuration file.

    Closes-Bug: #1478996
