Adds new data migration ``migrate_to_hardware_types`` that will try to
migrate nodes from classic drivers to hardware types on upgrade. Nodes
that cannot be migrated are skipped. This may happen due to one of these
reasons:
* migration is not implemented for the classic driver,
* the matching hardware type is not enabled,
* one or more matching hardware interfaces are not enabled.
In the latter case, the new migration command line option
``reset_unsupported_interfaces`` can be used to reset optional interfaces
(all except for ``boot``, ``deploy``, ``management`` and ``power``) to
their no-op implementations (e.g. ``no-inspect``) if the matching
implementation is not enabled. Use it like::
ironic-dbsync online_data_migrations --option migrate_to_hardware_types.reset_unsupported_interfaces=true
This migration can be repeated several times to migrate skipped nodes
after the configuration is changed.

A classic driver implementation can now provide matching hardware type and
interfaces to enable automatic migration to hardware types. See `the
specification
<http://specs.openstack.org/openstack/ironic-specs/specs/approved/classic-drivers-future.html#automatic-migration>`_
for an explanation on how to do it.
.. note::
This feature will only be available until the classic drivers support
is removed (presumably in the Rocky release).
