Logging structure decisions

[LOHMgit]

We need to log to stdout because this is how Pachyderm will be able to track the logs from the container. So, I don't think that we need to set file related things. In terms of logging more generally, maybe we want to do something like this, but at a higher level for the API (such that all the scripts and API itself can import this). However, let's push that to a new PR. For now, I think something like the following would suffice:

import logging
logging.warning('Watch out!') # will print a message to the console
logging.info('I told you so') # will not print anything

[LOHMgit]

def get_logger():
module_name = file.split('/')[-1].split('.')[0]
#set the root logger to a debug level
logger = logging.getLogger(module_name)
logger.setLevel(logging.DEBUG)
logger.handlers = []
#set up a stream handler
s_handler = logging.StreamHandler()
s_handler.setLevel(logging.DEBUG)
log_format = logging.Formatter(fmt='%(asctime)s | %(levelname)s | %(message)s | %(name)s',
datefmt='%Y-%m-%d %H:%M:%S')
s_handler.setFormatter(log_format)
logger.addHandler(s_handler)
return logger

Here is how I was handling it before...

@LOHMgit I think we're mostly using print statements to modal now. Is there any advantage to doing this kind of logging?

@woodwardmw Does SIL have any centralized logging service that they use?
