Enable automatic migration for classic drivers to hardware types

The new online data migration in ironic will migrate nodes from classic drivers
to hardware types. However, it will skip nodes with one or more target
hardware interfaces not enabled. In the undercloud we don't enable certain
implementations that we do not support (e.g. "agent" RAID and
"ipmitool-shellinabox" console for the "ipmi" hardware type).
To allow the migration to work, set a special option to reset these
interfaces to their no-op equivalents ("no-raid", "no-console", etc).

+  - |
+    During an upgrade to this release, a migration of all nodes from classic
+    drivers to hardware types will be attempted. For some nodes it may result
+    in non-supported optional interfaces (like "agent" RAID or shellinabox
+    console) to be reset to their no-op implementations (like "no-raid" RAID or
+    "no-console" console). Nodes that cannot be upgraded will be skipped.
+    Manual upgrade will be required, since the classic drivers may be removed
+    in the Rocky release.
