    Disable nohz_full in a virtual env

    In VirtualBox, after unlock, SM has all of its services
    in 'initial' state.

    The reason for this is that SM will not proceed unless
    it detects there are no timer delays.

    This is particularly noticable for AIO-SX.

    By disabling nohz_full in virtual box, the timers are
    not delayed and SM is able to start up its services
    more quickly (5 seconds). Othwerwise SM initialization
    on a 4 core system can range from 10 minutes to 10 hours.

    Test Plan:
      Build/Bootstrap/Unlock Debian AIO-SX on virtualbox.
