One piece of information that might be helpful to expose at a higher level is the device that failed so that we can identify hardware that is failing frequently.

autotest: improve readability of logs.

This change prepends all ssh_run commands to a DUT with a
preamble that spews the run command to /var/log/messages
on the DUT. That will provide more context in case of a
DUT hang, reboot or other system failure what autotest
was up to.

autotest: improve readability of logs (2).

This change overrides logging.*() autotest output on the client,
which normally is diverted to a file (like in this instance
/usr/local/autotest/results/default/debug/client.0.WARNING)
to also be appended to /var/log/messages using the "logger"
command.

This change is purely client/DUT side.

Also a tiny bit of pylint cleanup.
