From: Punit Agrawal <punit1.agrawal@xxxxxxxxxxxxx>
The cyclictest.py module uses a temporary file to store the output
from "cyclictest" which is deleted at the end of the run. As the
collected log contains information that can be useful for development
or debugging, having the ability to persist the logs is useful.
With this goal, introduce a configuration option for the cyclictest.py
module, "savelogs", that can be used to enable persisting the
cyclictest output to a logfile. As the logs an be quite large, the
default is to not save them.
