Restrict scope of modification of root logger to logging_utils

[ananthrs1]

scope this modification down to get_logger method in logging_utils.py

logging.root.handlers = []
logging.basicConfig(level="WARN",
format='SystemLog: %(asctime)s:%(levelname)s : %(name)s : %(lineno)d : %(message)s',
stream=sys.stdout)

Like Dan Schwartz (@danrsc) pointed out, the modification should be something like this:

log = logging.getLogger(__name__)

log.setFormatter(...)
