There was a problem hiding this comment.
BTW, when using bufio.NewScanner, the bufio.ScanLines is already split function by default. We don't need to set it up again.

Problem:
When downloading ISO, the progress bar doesn't show well. The reason is that curl uses
\rto overwrite and print the progress bar.Solution:
We should consider the
\rcharacter as well when scanning. And add a tag to switch different printers to print the messages.Related Issue:
harvester/harvester#5990
Test plan:
Install it with PXE, and check progress bar should display correctly.
