Includes functionality for scanning and referring to partitions on
attached disks (i.e. snapshot images).
Fairly modular structure, so adding ZFS/LVM/etc... support in the future
should be easy.
The path is encoded as "/disk/bucket/component/path/to/file", e.g.
"/drive-scsi0/part/0/etc/passwd". See the comments for further
explanations on the design.

Add a watchdog that will automatically shut down the VM after 10
minutes, if no API call is received.
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'
files. This should be the foundation for a general file-restore
interface that is shared with block-level snapshots.
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
proxmox-backup-client.

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.

by using our DeflateEncoder
for this to work, we have to create wrapper reader that generates the crc32
checksum while reading.
also we need to put the target writer in an Option, so that we can take
it out of self and move it into the DeflateEncoder while writing
compressed
we can drop the internal buffer then, since that is managed by the
deflate encoder now

by changing the 'store' parameter of the restore api call to a
list of mappings (or a single default datastore)
for example giving:
a=b,c=d,e
would restore
datastore 'a' from tape to local datastore 'b'
datastore 'c' from tape to local datastore 'e'
all other datastores to 'e'
this way, only a single datastore can also be restored, by only
giving a single mapping, e.g. 'a=b'

The text 'had to upload [KMG]iB' implies that this is the size we
actually had to send to the server, while in reality it is the
raw data size before compression.

in commit `asyncify pxar create_archive`, we changed from a
separate thread for creating a pxar to using async code, but the
StdChannelWriter used for both pxar and catalog can block, which
may block the tokio runtime for single (and probably dual) core
environments
this patch adds a wrapper struct for any writer that implements
'std::io::Write' and wraps the write calls with 'block_in_place'
so that if called in a tokio runtime, it knows that this code
potentially blocks

This is just an optimization, avoiding to read the catalog into memory.
We also expose create_temporary_database_file() now (will be
used for catalog restore).
- new helper: lock_media_set()
- MediaPool: lock media set
- Expose Inventory::new() to avoid double loading
- do not lock pool on restore (only lock media-set)
- change pool lock name to ".pool-{name}"
so that a user can schedule multiple backup jobs onto a single
media pool without having to consider timing them apart
this makes sense since we can backup multiple datastores onto
the same media-set but can only specify one datastore per backup job

by adding the existing credential id to the 'excludeCredentials' list
this prevents the browser from registering a token twice, which
lets authentication fail on some browser/token combinations
(e.g. onlykey/solokey+chromium)
while is seems this is currently a bug in chromium, in a future spec
update the underlying behaviour should be better defined, making this
an authenticator bug

the current default is 'Preferred', which is not really useful, as the
(web) client can simply change this to discouraged, since the
webauthn_rs crate does not verify the 'user_verified' bit of the
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)
in any case, the current default is not helpful for security, but
makes loggin in harder, since the key will by default want to verify
the user
