    Add resource_class to fields in ironic node cache

    Per the discussion in [1], the ironic nodes added to the node cache in
    the ironic virt driver may be missing the required field resource_class,
    as this field is not in _NODE_FIELDS. In practice, this is typically
    not an issue (possibly never), as the normal code path uses a
    detailed list to sync all ironic nodes, which contain all fields
    (including resource_class). However, some code paths use a single
    node query with the fields limited to _NODE_FIELDS, so could result in a
    node in the cache without a resource_class.

    This change adds resource_class to _NODE_FIELDS.
