provide option to just show progress summary

for upload, an option like rclone to just have a summary of progress and not a pyout table. this summary could include just what pyout is showing:

- N of M files uploaded
- X files errored
- Z files digesting
- Y files uploading
- speed
- log location

this particular upload has received several http connection errors and the list of errors is growing. so a simple summary without showing the error fragments could be helpful.

this may also help decouple the jobs/threads and pyout
