verbose logging option to show same info as dry-run about lieer

[gauteh]

Hi, yeah, that would be nice. I think I am in favor of a command-line switch. Can't remember if it is currently possible to disable the bar, but maybe something that uses https://github.com/gauteh/lieer/blob/master/lieer/nobar.py with no output.

added a PR for this #245

For the progress bar --no-progress on it's own replaces tqdm with a .nobar/tqdm, but --no-progress --quiet removes that for the most logging friendly output. But then it misses stats on how long it took, but that can at least be added by an external script that is doing the logging & redirecting.

Better than redirecting stdout to a log file and stuff would be having logging set up in the config file so that all manual push/pull history operations can get automatically logged. That's a bit more work tho.
