For proxmox packages it works the same way as PVE, by retrieving the
changelog URL and issuing a HTTP GET to it, forwarding the output to the
client. As this is only supposed to be a workaround removed in the
future, a simple block_on is used to avoid async.
For debian packages we can simply call 'apt-get changelog' and forward
it's output.

As always, libapt is mocking us with complexity, but we can get the
approximate result we want by retrieving dependencies of all
to-be-updated packages and then seeing if they are missing.
If they are, we assume they will be installed.
For this, query_detailed_info is extended to allow reading details for
non-installed packages, and this is also exposed in
list_installed_apt_packages via 'all_versions_for'. This is necessary so
we can retrieve changelogs for such packages.
Note that we cannot retrieve all that information all the time, as
querying details for packages that aren't installed takes a rather long
time.

Avoids custom hardcoded logic, but can only be used for debian packages
as of now. Adds a FIXME to switch over to use --print-uris only once our
package repos support that changelog format.

To get package details for a specific version instead of only the
candidate.
Also cleanup filter function with extra struct instead of unnamed &str
parameters.

Depends on patched apt-pkg-native-rs. Changelog-URL detection is
inspired by PVE perl code for now, though marked with fixme to use 'apt
changelog' later on, if/when our repos have APT-compatible changelogs
set up.
list_installed_apt_packages iterates all packages and creates an
APTUpdateInfo with detailed information for every package matched by the
given filter Fn.
Sadly, libapt-pkg has some questionable design choices regarding their
use of 'iterators', which means quite a bit of nesting...
