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.

Previously only Datastore.Modify was required for creating a new
datastore.
But, that endpoint allows one to pass an arbitrary path, of which all
parent directories will be created, this can allow any user with the
"Datastore Admin" role on "/datastores" to do some damage to the
system. Further, it is effectively a side channel for revealing the
systems directory structure through educated guessing and error

This can slow things down by a lot on setups with (relatively) high
seek time, in the order of doubling the backup times if cache isn't
populated with the last backups chunk inode info.
Effectively there's nothing known this protects us from in the
codebase. The only thing which was theorized about was the case
where a really long running backup job (over 24 hours) is still
running and writing new chunks, not indexed yet anywhere, then an
update (or manual action) triggers a reload of the proxy. There was
some theory that then a GC in the new daemon would not know about the
oldest writer in the old one, and thus use a less strict atime limit
for chunk sweeping - opening up a window for deleting chunks from the
long running backup.
But, this simply cannot happen as we have a per datastore process
wide flock, which is acquired shared by backup jobs and exclusive by
GC. In the same process GC and backup can both get it, as it has a
process locking granularity. If there's an old daemon with a writer,
that also has the lock open shared, and so no GC in the new process
can get exclusive access to it.
So, with that confirmed we have no need for a "half-assed"
verification in the backup finish step. Rather, we plan to add an
opt-in "full verify each backup on finish" option (see #2988)

A client can omit uploading chunks in the "known_chunks" list, those
then also won't be written on the server side. Check all those chunks
mentioned in the index but not uploaded for existance and report an
error if they don't exist instead of marking a potentially broken backup
as "successful".
This is only important if the base snapshot references corrupted chunks,
but has not been negatively verified. Also, it is important to only
verify this at the end, *after* all index writers are closed, since only
then can it be guaranteed that no GC will sweep referenced chunks away.
If a chunk is found missing, also mark the previous backup with a
verification failure, since we know the missing chunk has to referenced
in it (only way it could have been inserted to known_chunks with
checked=false). This has the benefit of automatically doing a
full-upload backup if the user attempts to retry after seeing the new
error, instead of requiring a manual verify or forget.
