grafana + clickhouse模板变量使用all

在使用dashboard的模板变量时，选择all时，如下clickhouse查询语句查询，无法解析正确执行：

SELECT orderId,OrderJsonStr FROM xdatabase."xxxx_table" WHERE   ( createTime  >= $__fromTime AND createTime <= $__toTime )  AND orderId IN (${orderId}) ORDER BY orderId DESC LIMIT 300

优化为：

SELECT orderId,OrderJsonStr FROM xdatabase."xxxx_table" WHERE   ( createTime  >= $__fromTime AND createTime <= $__toTime )  AND $__conditionalAll(orderId IN (${orderId:singlequote}), $orderId) ORDER BY orderId DESC LIMIT 300

可正常执行，选择all时语句变为 1=1
