Chef::Mixin::Properties::ClassMethods#identity_properties

Set the identity of this resource to a particular set of properties.

This drives #identity, which returns data that uniquely refers to a given
resource on the given node (in such a way that it can be correlated
across Chef runs).

This method is unnecessary when declaring properties with `property`;
properties can be added to identity during declaration with
`identity: true`.

```ruby
property :x, identity: true # part of identity
property :y # not part of identity
```

If no properties are marked as identity, "name" is considered the identity.
