To delete an attribute from an existing Chef Server node, the handler uses Chef's REST API. The handler first retrieves the users private key from the specified location so that it can then be used to sign the REST request. The handler then retrieves the node that will be updated to get all of the attributes that are currently attached to it, looks for a 'normal' attribute key that matches the Attribute Name parameter and deletes it from the object. The updated node object is then re-posted to the Chef Server to apply the changes to the node attributes on the Chef Server. And errors that are encountered during the process are caught and re-rasied by the handler.
Name of the node that the attribute will be removed from.
