    RedHat: Retry umount /afs on systemd shutdown
    
    When systemd tries to stop openafs-client.service during system
    shutdown, our 'umount /afs' will fail if someone else is accessing
    /afs. The openafs-client.service unit is then marked as deactivated
    (and failed), and the shutdown sequence proceeds.
    
    After all services have been stopped, systemd-shutdown tries to kill
    all remaining processes with SIGTERM and then SIGKILL, waiting
    DefaultTimeoutStopSec seconds (default: 90) for them to die. If there
    are unkillable processes running (for example, afsd), this results in
    at least a 3-minute delay.
    
    It's hard to make sure there are no processes accessing /afs during
    the shutdown sequence, since that could include processes outside of
    defined systemd units. So some processes may be shutting down in
    parallel with openafs-client.service, and so it's a race whether there
    are /afs-using processes when we try to umount /afs.
    
    To avoid the most common cases of this, retry our umount during
    openafs-client's ExecStop for $UMOUNT_TIMEOUT seconds (default: 30),
    to give other /afs-using processes a chance to go away. Only do this
    if the system is shutting down (according to 'systemctl
    is-system-running'), so users don't see a long delay running
    'systemctl stop openafs-client' during normal system operation.
