stderr log file

[nbari]

Create 3 log options, keep it simple by just adding an option to write stderr and not merging it into the default log

If log, stdout & stderr will be combined. (default and used also for a custom logger)

log:
  file: /var/log/app/access.log
  age: 86400
  num: 3
  size: 1

if stderr_log stderr, the log file will contain only standard output and the standard error will be written to the defined file.

log:
  file: /var/log/app/access.log
  age: 86400
  num: 3
  size: 1
stderr:
  file: /var/log/app/error.log
  age: 86400
  num: 3
  size: 1

If only stderr there will be no stdout:

stderr:
  file: /var/log/app/error.log
  age: 86400
  num: 3
  size: 1
