Bug#963523: apt: show held packages status with 'apt list --upgradable' command

[Vipul]

May be better to separate package list in two sections, one for
upgradable and other for hold, if any package is on-hold. This way list
will look more clearer; and we can easily figure out list of hold
packages without looking for meta tag.

Bug#963523: apt: show held packages status with 'apt list --upgradable' command

[Vipul]

Package: apt
Version: 1.8.2.1
Severity: wishlist
Tags: upstream

Dear Maintainers,

Sometimes I hold some packages from being automatically upgraded using
'apt-mark hold ' command; but when I run 'apt list
--upgradable' command, there is no way to know which package has been
held. Indeed, I can know list of held package by running 'apt-mark
showhold' command. But isn't it would be nice if these information will
also be available with 'apt list --upgradable' command as meta
information along with package?

May be just adding meta tag along with package would be enough.

$ sudo apt-mark hold riot-desktop
riot-desktop set on hold.

## Actual output of apt list command.

$ apt list --upgradable

## Instead, we can add a little meta tag along with riot-desktop package, or 
something similar.
