This test installs a specified test image onto a servo-connected DUT.
The principle purpose is to allow installing a known-good image onto
a wedged unit that would otherwise have to be re-imaged manually.

Here is the command to install a recovery image with a locally attached
servo:
    run_remote_tests --args="image=$IMAGE_PATH" \
                     --servo --remote=$IP_ADDRESS --board=$BOARD \
