    Fail-fast if the undercloud-passwords.conf file is missing

    On undercloud updates/upgrades, if the undercloud-passwords.conf
    file was deleted or moved it will break some services because there
    are passwords that cannot be changed. This validates that the file
    exists and stops immediately with a message explaining the problem
    if the file is missing.
