Better progress bar handling for OTP

[AnomalRoil]

RELEASE_NOTES=[BUGFIX] Do not print OTP progress bar if not in terminal
RELEASE_NOTES=[UX] Use new progress bar for OTP expiry time

This is making the expiry time for OTP visually go from 0 to expiry time in terminal, but prevents printing the progress bar when not in a terminal.

I also replaced the special handling of the remaining time until expiry to use Truncate instead.

Sadly, I'm yet again adding some "special handling" to detect whether we are in a terminal or not. We might want to heavily refactor all such things.

This fixes #2017.

Looks good, thanks. But I'd suggest some small changes.

Thanks!

Is there any release schedule? I wanna use this feature! 😆

[dominikschulz]

Cutting new releases has become very easy. We can do one soon. Probably this week.

This may be a silly question, but how do I stop the OTP progress bar introduced in 1.13.0 after I used the OTP code? I don't want to wait N seconds before I can run the next gopass command in the interactive shell, and Ctrl+C quits the whole shell.

@AnomalRoil ?

Personally I don't put OTP into my stores so I don't use this.

[AnomalRoil]

Mhhh I personally never use the interactive shell, so I didn't realize we needed a way to do that.
I could had a key binding to q maybe to quit it?

[mirkonasato]

q to quit would be great!

[dominikschulz]

@mirkonasato I'm sorry for that inconvenience. I have just reproduced it and we definitely need a way to abort the progress bar w/o killing gopass.

I've added a fix in #2041. 👍🏻
