Add way to get S.M.A.R.T status for disks in hosts

Feature Request

Description

talosctl already has a number of functions, such as get disks to list disks, but there is no way to get the SMART status for them. I understand that Talos nodes are meant to be easily replaceable and ephemeral, but it would be helpful for certain services, such as CEPH, to be able to tell when disks are having issues or need to be replaced, before potentially losing critical data.

Obviously support for NVME and non NVME drives would have to be considered, but it is doable with smartctl in linux.

Thanks!

You can also get this with a deamonset and a priviliged container with smartctl installed and push the informations to prometheus for example.

@Syntax3rror404 thats true, but when you're working around with the cli it would be nice to have something like talosctl -n 1.1.1.1 get smart or something and see directly on the host but yea that is a workaround too :)

We could use https://github.com/anatol/smart.go/tree/main to pull the data.

Note: this library has issue with not setting CLOEXEC on open files.
