Add logging configuration

The tempest log can help developers analyze tests but
there is no option in run_tests.sh to enable logging output now.
This adds a logging configuration file and options in run_test.sh
and enables developers to get the tempest log more easily.

Implements: blueprint add-logging-configuration
