> Add a new field in FileSystem.Cache.Key to affect hashCode() and equals(). This field could be specified when constructing a Key
>  * For new users, they are able to control the hash code generation with respect to this field (could be a security string/token/object...), which may contain access (read/write/list...) and/or expiration time ...
>  * For old users, this field defaults to null and is not honored in hashCode() and equals()
