Bug Description

Currently there is no way to provision software RAID for nodes without a dedicated hardware controller.

Removing the requirement for a hardware RAID controller by implementing software RAID on compute nodes reduces initial hardware costs but retains some resiliency, allowing a good "trade-off" between cost and features.

It would be useful to be able to do this to add resiliency for compute nodes for example.

I suppose it would be good to use the command:

ironic node-set-target-raid-config

and then feed it a simple json file like:

 "logical_disks": [
                    "size_gb": "MAX",
                    "raid_level": "1",
                    "is_root_volume": true

Additionally, this would need implementing as a clean step in the default IPA hardware manager. We should expect that the disks would be cleaned on every deploy.
