Backport PR #16091 to 202211
Why I did it
watchdogutil uses platform API watchdog instance to control/query watchdog status. In Nvidia watchdog status, it caches "armed" status in a object member "WatchdogImplBase.armed". This is not working for CLI infrastructure because each CLI will create a new watchdog instance, the status cached in previous instance will totally lose. Consider following commands:
Work item tracking
How I did it
Use sysfs to query watchdog status
How to verify it
Manual test
Unit test
Which release branch to backport (provide reason below if selected)
Tested branch (Please provide the tested image version)
