Feature Request: Reduce log size

[gitthangbaby]

Is your feature request related to a problem? Please describe.
Too much logging. Synology not able to scrap the log as it's beyond its limits.

Describe the solution you'd like
New CLI parameter -q to avoid the fancy temporary output e.g. "Loaded 100/300"

Describe alternatives you've considered
I've emptied the util/print_return() function. That's where the solution could be added.

Additional context
Incomplete output is captured ending in the middle of "Parsing ID 7" sentence on line 30000. First i've tried -nc parameter or "Time between imports" (like in some other cases, unknown unit - seconds, minutes) but that doesn't seem to impact logging. Since the logs are captured, it grabs too many of the following lines:

• Loaded:
• Processing:
• Filtering:
• Parsing ID
  I suggest we have a console friendly mode "quiet" to avoid the temporary progress output which is not needed in the log archives.
