Switch non-vendor parts admin guide to hardware types

This change makes the admin guide use hardware types for examples and
explanations. The in-band inspection document was updated with recent
changes.

Vendor driver documentation requires more careful review, and ideally
should be updated by vendor representatives.

The bare metal node needs to use a driver that supports RAID

out-of-band.
The bare metal node needs to use a hardware type that supports RAID
configuration. RAID interfaces may implement RAID configuration either in-band
or out-of-band.
In-band RAID configuration is done using the Ironic Python Agent
ramdisk. For in-band RAID configuration using agent ramdisk, a hardware
manager which supports RAID should be bundled with the ramdisk.
The drivers supporting RAID configuration could be found using the CLI
Whether a node supports RAID configuration could be found using the CLI
command ``openstack baremetal node validate <node-uuid>``.

* Operator configures the bare metal node with a driver that has a ``RAIDInterface``.
* Operator configures the bare metal node with a hardware type that has
a ``RAIDInterface`` other than ``no-raid`` (``None`` for classic drivers).
* For in-band RAID configuration, operator builds an agent ramdisk which
supports RAID configuration by bundling the hardware manager with the
