Filter out temperature=255 at this stage rather than in clients who
use us
Allow hddtemp to output a simpler format if --no-device --numeric is
requested
Ignore idle disks as well in order not to bring them out of idle mode
and thus reset timer
Migrate smart-intercept-spindown and smartctlnvme into this repo from
my ansible-initial-server-setup playbooks, so they can be published in
a self-contained repo. Ansible then distributes these files anyway
via including this repo.
This enables us to get rid of the spindown test code we duplicated
here, plus ensure we're actually distributing smartctlnvme
