switch from hddtemp to smartmontools

hddtemp is used to monitor the hard disks temperature. This package is dormant and is not available on debian12.
It is recommended to use smartmontools instead.
This commit creates the snmp endpoint to retrieve the hard drive temperatures using Smartmontools, and remove the hddtemp deployment code from the playbooks.
