 Updated ErrorResponse to serialize its "status" field as a JSON string rather than as a number for compliance with RFC 7644. Deserialization of this field is backwards compatible and will accept either a number or a string. Clients expecting the "status" field as a JSON string (including older SCIM 2 SDK clients) will need to be updated for compatibility.
