[autotest] Add a new dut_status command.
This adds a new dut_status command that can report on whether a DUT
was working or broken at a given time. Status is determined by
looking backwards in time for a job result (e.g. a failed Repair
job) that indicates the DUT's working or broken status.
BUG=None
TEST=Run against various DUTs with a known status, run new unit tests
