The script was originally introduced in OSH [1] to work around a
limitation where `keystone-manage bootstrap` would not update endpoints
once created. That limitation was resolved 8 years ago when upstream
keystone added endpoint updates support to bootstrap [2].
Additionally, the OPENSTACK_CONFIG_FILE, OPENSTACK_CONFIG_DB_SECTION,
and OPENSTACK_CONFIG_DB_KEY environment variables the script relied on
are no longer available in the db-sync Job.
