daisydog: add a uma stat to track watchdog startup failures |
||||||||
Issue descriptionas part of the cleanup work for bug 667075 , we should add a uma stat to track how often the watchdog service fails to start up properly. we don't think it's a problem in practice, but we want to be confident before we start making the failure a soft one for the purposes of booting in a VM.

Add a metric to track this better over all devices so we can see if we need to add more logic here in the future.
