To support nested BucketComponents, it is necessary to dedup them, as
otherwise two components like:
/foo/bar
/foo/baz
will result in /foo being shown twice at the first hierarchy.
Also make the size property based on index and optional, as for example
/foo in the example above might not have a size, and bar/baz might have
differing sizes.

we try to load the correct media in a loop until we find the correct tape.
when encountering an error or wrong tape, we want to log that (and send
an email if one is set) that requests the correct tape.
while trying to avoid printing the same errors more than once in a row,
we had at least one case (starting with an empty tape in the drive)
which would not print/send any tape request.
reworking that code to use a custom 'TapeRequest' enum, which contains
the state + error message, and a helper that prints and sends an email
when the state changes
this reduces the change check/log to a single variable, instead of 4

Implemented as a seperate struct SeekableCachedChunkReader that contains
the original as an Arc, since the read_at future captures the
CachedChunkReader, which would otherwise not work with the lifetimes
required by AsyncRead. This is also the reason we cannot use a shared
read buffer and have to allocate a new one for every read. It also means
that the struct items required for AsyncRead/Seek do not need to be
included in a regular CachedChunkReader.
This is intended as a replacement for AsyncIndexReader, so we have less
code duplication and can utilize the LRU cache there too (even though
actual request concurrency is not supported in these traits).

this makes it possible to only restore some snapshots from a tape media-set
instead of the whole. If the user selects only a small part, this will
probably be faster (and definitely uses less space on the target
datastores).
the user has to provide a list of snapshots to restore in the form of
'store:type/group/id'
e.g. 'mystore:ct/100/2021-01-01T00:00:00Z'
we achieve this by first restoring the index to a temp dir, retrieving
a list of chunks, and using the catalog, we generate a list of

in proxmox-backup-proxy, we log and discard any errors on 'accept',
so that we can continue to server requests
in proxmox-backup-api, we just have the StaticIncoming that accepts,
which will forward any errors from the underlying TcpListener
this patch also logs and discards the errors, like in the proxy.
Otherwise it could happen that if the api-daemon has more files open
than the proxy, it will shut itself down because of a
'too many open files' error if there are many open connections
(the service should also restart on exit i think, but this is
a separate issue)

if a datastore or root is not used directly on the pool dir
(e.g. the installer creates 2 sub datasets ROOT/pbs-1), info in

dataset, which has no iostats itself in /proc/spl/kstat/zfs/

Includes methods to start, stop and list QEMU file-restore VMs, as well
as CLI commands do the latter two (start is implicit).
The implementation is abstracted behind the concept of a
"BlockRestoreDriver", so other methods can be implemented later (e.g.
mapping directly to loop devices on the host, using other hypervisors
then QEMU, etc...).
Starting VMs is currently unused but will be needed for further changes.
The design for the QEMU driver uses a locked 'map' file
(/run/proxmox-backup/$UID/restore-vm-map.json) containing a JSON
encoding of currently running VMs. VMs are addressed by a 'name', which
is a systemd-unit encoded combination of repository and snapshot string,
thus uniquely identifying it.
Note that currently you need to run proxmox-file-restore as root to use
this method of restoring.

Signed-off-by: Stefan Reiter <s.reiter@proxmox.com>
Implements the base of a small daemon to run within a file-restore VM.
The binary spawns an API server on a virtio-vsock socket, listening for
connections from the host. This happens mostly manually via the standard
Unix socket API, since tokio/hyper do not have support for vsock built
in. Once we have the accept'ed file descriptor, we can create a
UnixStream and use our tower service implementation for that.
The binary is deliberately not installed in the usual $PATH location,
since it shouldn't be executed on the host by a user anyway.
For now, only the API calls 'status' and 'stop' are implemented, to
demonstrate and test proxmox::api functionality.
Authorization is provided via a custom ApiAuth only checking a header
value against a static /ticket file.
Since the REST server implementation uses the log!() macro, we can
redirect its output to stdout by registering env_logger as the logging
target. env_logger is already in our dependency tree via zstd/bindgen.

This allows switching the base user identification/authentication method
in the rest server. Will initially be used for single file restore VMs,
where authentication is based on a ticket file, not the PBS user
backend (PAM/local).
To avoid putting generic types into the RestServer type for this, we
merge the two calls "extract_auth_data" and "check_auth" into a single
one, which can use whatever type it wants internally.

For now it only supports 'list' and 'extract' commands for 'pxar.didx'

This is packaged as a seperate .deb file, since for block level restore
it will need to depend on pve-qemu-kvm, which we want to seperate from

I made some comparision with bombardier[0], the one listed here are
30s looped requests with two concurrent clients:
[ static download of ext-all.js ]:
lvl avg / stdev / max
none 1.98 MiB 100 % 5.17ms / 1.30ms / 32.38ms
fastest 813.14 KiB 42 % 20.53ms / 2.85ms / 58.71ms
default 626.35 KiB 30 % 39.70ms / 3.98ms / 85.47ms
[ deterministic (pre-defined data), but real API call ]:
lvl avg / stdev / max
none 129.09 KiB 100 % 2.70ms / 471.58us / 26.93ms
fastest 42.12 KiB 33 % 3.47ms / 606.46us / 32.42ms
default 34.82 KiB 27 % 4.28ms / 737.99us / 33.75ms
The reduction is quite better with default, but it's also slower, but
only when testing over unconstrained network. For real world
scenarios where compression actually matters, e.g., when using a
spotty train connection, we will be faster again with better
compression.
A GPRS limited connection (Firefox developer console) requires the
following load (until the DOMContentLoaded event triggered) times:
lvl t x faster
none 9m 18.6s x 1.0
fastest 3m 20.0s x 2.8
default 2m 30.0s x 3.7
So for worst case using sligthly more CPU time on the server has a
tremendous effect on the client load time.
Using a more realistical example and limiting for "Good 2G" gives:
none 1m 1.8s x 1.0
fastest 22.6s x 2.7
default 16.6s x 3.7
16s is somewhat OK, >1m just isn't...
So, use default level to ensure we get bearable load times on
clients, and if we want to improve transmission size AND speed then
we could always use a in-memory cache, only a few MiB would be
required for the compressable static files we server.

response in that case
setting this to 'Required' is not really useful either at the moment,
since a user can have a mix of different authenticators that may or
may not support user verification
there is ongoing discussion in the crate how to handle that[0]
we could probably expose this setting(discouraged/required) to the user/admin
and save it to the credential and allow only registering credentials
of the same type or filter them out on login (i.e. if there is an
authenticator that can handle userVerification, require it)
