Adding backup script and dico updates

ref #31661
ref #31660

How it works :

Update the backup configuration in gen_config
set the backup directory (to host the backups)
set if you only want to backup tagged VMS
set if you want to backup unused images to
reconfigure your hapy server

run the backup script with no options

First the script will backup the unused images (if neede) and the non persistent
images to BACKUP_DIR/one/datastores/<STORAGE_DS>/<REAL_IMAGE_FILE_NAME>.

Then script will perform a "disk-saveas" on each disk of each Virtual
Machine.

Then it will backup the new image files under the original name, in the
write place. If your disk is non persistent it will backup it into
BACKUP_DIR/one/datastores/<SYSTEM_DS>/<VMID>/disk.<DISK_ID>.

If it's persistent it will save the symlink into
BACKUP_DIR/one/datastores/<SYSTEM_DS>/<VMID>/disk.<DISK_ID> keeping the original
link, then it will follow the link to backup the real disk file into
BACKUP_DIR/one/datastores/<STORAGE_DS>/<LINKED_FILE_NAME>.

The script will save the deployment files also.

At the end the BACKUP_DIR will look like this :
/mnt/sauvegardes/
