      operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.

      运算符表示与一组值之间的关键关系。有效的运算符包括 In、Not、Exists 和 DoesNotExist。

      values 是一个字符串值数组。如果运算符为 In 或 NotIn，则 values 数组不能为空；如果运算符为
      Exists 或 DoesNotExist，则 values 数组必须为空。在执行策略性合并补丁（strategic merge patch）操作时，该数组会被替换。
