Recover DUTS is a utility that only runs on test images. It periodically
runs a set of hooks to ensure the DUT (Device Under Test) can correctly
connect and attempts to programmatically recover a malfunctioning DUT.

Recover DUTs is "enabled" only when /mnt/stateful/.lab_machine exists.

In order to add a hook, add an executable script in the hooks/ dir that ends with
.hook suffix. It can be written in anything that is executable by a test image --
Python, Dash script or a binary program.

Hooks that fail result in logs @ /var/log/recover_duts_log.

The init script to start recover_duts is:
    src/platform2/init/upstart/test-init/recover_duts.conf
