Bug#910893: apt: Add apt install option to revert conffiles

[Jeremy Bicha]

Source: apt
Version: 1.7.0
Severity: wishlist

I think it would be nice if `apt install` offered an easier option for
users to revert their conffiles back to the Debian defaults.

So maybe you could have something like

$ apt install --revert-conffiles

that would actually do:

$ apt install --reinstall -o Dpkg::Options::="--force-confask,confnew,confmiss"

It would be a lot easier to remember and use.

Thanks,

dpkg's --force-confask might be all we need really. That way it still
asks you about changes with the option to view a diff.
