> Priority: Minor
>
> # 元数据操作/存储组操作/创建存储组：“{color:#ff0000}存储组节点名只支持中英文字符、数字、下划线和中划线的组合{color}” 应改为
> “存储组节点名支持中英文字符，下划线， 如果要包含其他字符或纯数字，需要用反引号引起来”
> # 元数据操作/存储组操作/查询存储组： 显示结果需要修改，目前show storage
> group时，还会显示region的副本数和time_partition_interval
> # 执行count nodes时，结果显示 | count(nodes) | 而不是 |count|
> # 执行count devices时，结果显示 |count(devices)| 而不是|count|
> # 执行 count timeseries， 结果显示 |count(timeseries)| 而不是|count|
