All log messages are written to stderr

[gaurav517]

Describe the bug

Currently all log messages are written to stderr which means all messages are interpreted as error messages by aggregators/log-forwarders. For example, logs are displayed as errors by google stackdriver.

Although fix should be in logrus (sirupsen/logrus#403), they don't seem interested in fixing this. So, either this would need change of logging util or some workaround given in the thread.

Expected behavior

Based on log levels, they should be written to stdout or stderr.
