-use "lunX" for volume name.
previously it was only the lun number, and it conflict with current syntax to disk alloc disk size.
-scsi-ls return size in Gb, so we need to convert to bytes
-small cleanups

no need to use volume_size_info, we can use generic volume_size_info from Plugin. (file_size_info)

Currently, if a storage have an infinite timeout (nfs hard option or iscsi with high timeout for failover),
and if the storage is down or is doing ha failover with dual controller
- pvestatd hang on storage_info. (So pve-manager see the host as down, and hang on differents parts, gui,rrds display)
- pvedaemon hang on differents place (storage disk list,vm_status, hardware info,...)
- I also see a lot of qemu-img info process hanging in uninterruptible sleep state with iscsi storage.
This patch add a check to see if the storage is accessible.
For nfs and iscsi : ping with a timeout of 2 second. (Maybe this can be polish with some kind of filesystem/storage read test with timeout...)
Default for other storage plugins is to check nothing. (not a problem with sheepdog,ceph,libiscsi... as commands have timeout)
