Support md-raid
Feature Request
There are many dedicated cloud providers offers to us the servers with two or more disks. Many of them do not have the hardware raid controllers.
It will be very nice to have softraid on the talos platform.
Thank you.
Supporting MD RAID is not only nice to have, it's mandatory in bare metal setups. Could it be possible to configure RAID out of Talos (ie. using a rescue OS) and let Talos use MD's autodetect feature or kernel command line to start the volumes ?
Having a RAID1 setup for all drives to boot off of would be great too.

Look at Hetzner, OVH, Scaleway. I understand nodes should be disposable, but if we can avoid failure at first it's always better.
Also some IO intensive workload require local disk. The local volume can be handled with CSI driver, but no RAID for the rootfs increase points of failure.
I would like to use Talos Linux in my home lab, but I can't. Since reliability is very important when there are not many servers.
I noticed that mdadm was added as extension in this commit: https://github.com/siderolabs/extensions/commit/7618f8ff99844db86c959a924dff001698afa923. I imagine this is one step closer to software raid support. What remains to be done before this is fully supported?
