we want this, because the model in /sys/block/<device>/device/model
is limited to 16 characters
and since the model is not always in the udevadm output (nvme),
also read the model from the model file as fallback

since we iterate over the entries in /sys/block
it makes sense to use this path
this should fix#1099
because udevadm does not take
-n cciss!c0d0 (because it only looks in dev for this)
but takes
-p /sys/block/cciss!c0d0

refactored the wear level parsing into its
own function, where we can now define a
vendor <-> attribute id
mapping

instead of parsing the output of smart in two places,
give get_smart_data a flag if we only want health
this fixes a bug (not on the bugtracker), where
an ssd with disabled smart had an empty string as health
in the gui

the smart checks are only needed for the API call(s) that
list all disks and their status, but get_disks is also used
in disk usage checks and in the Ceph code, where the smart
status is completely irrelevant.
drop the implicit skipping of smart checks if $disk is set,
since we have an explicit parameter for this now.
because we never ever want to die in get_disks because of a
single disk, but the nodes/xyz/disks/smart API path is
allowed to fail if a disk device is unsupported by smartctl
or something else goes wrong.
since smartctl uses the return value to encode
disk health status (such as failure in the past)
we cannot die there, but have to parse the returncode

this adds the functions for listing the disks (mostly copied from
the ceph code), checking if a disk is a valid blockdevice, if it
is used/in a zfs pool/as an lvm pv, and an init function (just to add a gpt header;
this is important if one wants to use a fresh disk for ceph journals)
