[Bug 2080277] [NEW] FFe: lxd-installer should prompt before installing LXD

[Simon Déziel]

Public bug reported:

* Problem description:

It is quite easy to accidentally trigger the on-demand installation of
LXD's snap which takes a while. This is something that can, for example,
happen inside a LXD instance where the operator didn't notice the
instance was "entered". Something:

$ lxc launch ubuntu-minimal:noble c1
$ lxc shell c1 # accidentally enter `c1`
# lxc list     # try to interact with LXD in the host but mistakenly triggers lxd-installer

This last step is taking a while because multiple snaps need to be
installed due to that `lxc list` being run in the wrong environment
(instance instead of host). This is why
https://bugs.launchpad.net/ubuntu/+source/lxd-installer/+bug/2073941 and
https://discourse.ubuntu.com/t/when-an-lxc-command-is-used-on-a-system-
without-lxc-lxd-lxd-is-immediately-installed-should-it-be-that-way/46570
were opened/reported.

* Motivation for the FFe:

A better behavior would be for `lxd-installer` to detect if there is a
terminal and if yes, prompt for a confirmation before doing the lengthy
installation process. If no terminal is detect, it should assume that
LXD is to be installed on-demand (current behavior). That is what
https://code.launchpad.net/~sdeziel/ubuntu/+source/lxd-
installer/+git/lxd-installer/+merge/471653

* Additional information:

lxd-installer authoritative sources live at
https://code.launchpad.net/~git-ubuntu-import/ubuntu/+source/lxd-
installer/+git/lxd-installer/+ref/ubuntu/devel so this is not a new
upstream release per se. As such, the only changelog would be:

  * scripts/lxc: ask before proceeding if interactive (LP: #2073941, LP:
#2080277)

This changelog and the associated changes are being proposed for merging
in https://code.launchpad.net/~sdeziel/ubuntu/+source/lxd-
installer/+git/lxd-installer/+merge/471653

The changes themselves are simply to prompt for confirmation before
proceeding with the lengthy installation if a terminal is detected.
