d32a8652bd file-restore-daemon: add disk module
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.

dd9cef56fc file-restore-daemon: add binary with virtio-vsock API server
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.
