This commit adds a Log() class for the functional test
suite. This class provides several static methods for
logging information during a test run. The data logged
is often useful for debugging failed tests.
Example usages:
Log.log_debug('Running test %s' % test name)
except Exception as e:
Log.log_error(e)
Both the log level and log file are configurable. By
default, the functional tests will log all messages of
criticality LOG_WARNING or higher to libcgroup-ftests.log.
These settings can be overridden by the following command
line options:
-l LOGLEVEL, --loglevel LOGLEVEL
-L LOGFILE, --logfile LOGFILE
