Software RAID (MDRaid) installation

[mmakarov-muse]

Hi.
As I researched, Talos can not be installed to MDRaid disk automatically.
It would be perfect to be able to install Talos to software raid.
Config can looks like:

machine:
  mdraid:
    mode: raid1
    name: md0
    devices:
      - /dev/sda
      - /dev/sdb

  install:
    disk: /dev/md0
    image: ghcr.io/siderolabs/installer:v1.7.0
    bootloader: true
    wipe: false
