Updated utils to the latest version. This version of utils has less

logging at info level and as such no longer prints out the celery task
timing which are found to be use to find out if a tasks has been called
but also the timing for the task. Added an extra timing message for
celery tasks so that it can be determined if the these are less frequent
than the API calls and provide more useful information
