Add separate `-q`/`--quiet` flag

[Sami Kankaristo]

-y/--yes doesn't usually suppress all output, it just automatically answers "yes" to all prompts.

It would be nice to have a version of -y, which shows normal output (to monitor progress, etc.), but still suppress all prompts.

So, maybe a separate "quiet" flag (-q/--quiet) for suppressing all output (which would also imply -y)? This is how e.g. apt and dnf/yum do things.

Yeah! I can see this being useful, it would be more intuitive too.
