    Add sssd systemd service file override

    sssd is monitored by pmon. But currently the Restart option in its
    systemd service file is set to on-failure. This sometimes causes
    systemd and pmon to fight to restart the service when it fails. All
    processes monitored by pmon should have Restart set to "no".

    This change added a systemd override file to set Restart to "no" for
    sssd service.

    Test Plan:
    PASS: Standard system deployment.
    PASS: Check sssd Restart option using "systemctl cat sssd", verify
          Restart option is set to "no", as following:

          # /etc/systemd/system/sssd.service.d/sssd-stx-override.conf
          [Service]
          # pmond monitors sssd service
          Restart=no
    PASS: Kill sssd process, verify pmon restart it successfully by
          tailing pmon.log, and verify sssd is running by "systemctl
          status sssd" command.
