(Improvement) Improve logging

[phahulin]

• What is it? (leave one option)

  • (Improvement) of existing functionality

• What was the root cause of the problem originally / what feature was missing? Small improvements to error messages and logging:

1. On errors, write log both to stdout and stderr, it makes it easier to see time-ordered log in a single file.

2. In some parts of the code createResponseObject(ok, err) is called passing error messages (string) as a second argument, however when logging, err expected to be an object and error message is expected to be in err.msg. This leads to undefined error messages in logs
