Stefan Reiter 2fd2d29281 file-restore: don't list non-pxar/-img *idx archives
These can't be entered or restored anyway, and cause issues with catalog
files for example.

Also a clippy fix.

Stefan Reiter b13089cdf5 file-restore: add 'extract' command for VM file restore
The data on the restore daemon is either encoded into a pxar archive, to
provide the most accurate data for local restore, or encoded directly
into a zip file (or written out unprocessed for files), depending on the
'pxar' argument to the 'extract' API call.

Stefan Reiter 801ec1dbf9 file-restore(-daemon): implement list API
Allows listing files and directories on a block device snapshot.
Hierarchy displayed is:

/archive.img.fidx/bucket/component/<path>
e.g.
/drive-scsi0.img.fidx/part/2/etc/passwd
(corresponding to /etc/passwd on the second partition of drive-scsi0)

Stefan Reiter 58421ec112 file-restore: add basic VM/block device support
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.

Stefan Reiter 9fe3358ce6 file-restore: allow specifying output-format
Makes CLI use more comfortable by not just printing JSON to the
terminal.

Dominik Csapak 76425d84b3 file-restore: add binary and basic commands
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.

/block subdir for .fidx files, seperate binary and package]
