BentoML

Hi Shihgian, for 1.0, we moved to a more standardized way of handling logs in BentoML. The default behavior is only logging to stdout, which works nicely with most cloud native setup. User can also choose to configure logging behavior with the python standard logging library for the “bentoml” logging namespace: <https://docs.bentoml.org/en/latest/guides/logging.html#logging-configuration>

Here’s a quick example mimicking the 0.13 behavior:
```import logging
from logging.handlers import RotatingFileHandler

logger = logging.getLogger('bentoml')
handler = RotatingFileHandler('my_log.log', maxBytes=2000, backupCount=10)
logger.addHandler(handler)

svc = bentoml.Service(...)
...```
