ChangBo Guo(gcb) 6b20fa8597 Improvement of logging acorrding to oslo.i18n guideline
1. Use translation marker functions, their argument must just be a string
2. Any message with more than one variable should use named
   interpolation instead of positional to allow translators
   to move the variables around in the string to account for
   differences in grammar and writing direction.
3. String interpolation should be delayed to be handled by the logging
   code, rather than being done at the point of the logging call.
For more details, please refert to oslo.i18n guideline [1]

Note: this commit doesn't touch test code.
