[PATCH pve-storage 2/9] luncmd: lio: fix LUN ops failing when passing nonstandard LUN path

["Max R. Carrara" <m.carrara@proxmox.com>]

For ZFS-over-iSCSI, all volumes and LUNs are usually created in the
format of 'vm-100-disk-0', 'vm-420-disk-2', etc.

However, it is possible to create a volume with a nonstandard volume
name, for example through `pvesh`:

    pvesh create /nodes/localhost/storage/zfs-iscsi-lio/content \
        --filename vm-110-disk-2-foo-bar-baz.raw \
	--size 4G \
	--vmid 110

Note that the main culprit here is actually the '.raw' suffix, because
'\w' doesn't match on periods, apparently.

Rather than restricting the API to match our preferred format (and
potentially break things), carefully make the regex that matches on
the LUN path less restrictive by also allowing to match on periods.
