    keyword=new alarm to check if DAQ is alive

    Runs 3757 - 3760 are DAQ tests during the access to fix cryo issues.

    There's been an ocassional problem that the DAQ dies and shift workers
    don't realize it for an hour or so. I've made a new alarm which checks
    if the DAQ has crashed and makes an audible alarm. Let's hope no false
    alarms. The logic that sounds an alarm is:

    1. The event builder is running (in process list) and is in state
    "active" (run in progress) with DAQ config TWOARM.
    2. The deadtime is 100%.
    3. 1 & 2 re-checked for 2 minutes to account for time lags at the end of
    a run which can lead to a false alarm.

    The code runs on adaql2 on a-onl account. It's called "checkdaq" and is
    re-started with a cron job.
