> Currently, it seems that the user can delete all data and timeseries by 
> {code:sql}
> delete timeseries root.*;
> {code}
> But this sql cann't delete all related storage groups. In addition, such an approach would be more time-consuming than simply deleting specified storage groups.
> So I believe it's better for `delete storage group' command to support wildcard.
> For example, all sgs and data can be deleted by one sql efficiently.
> {code:sql}
> delete storage group root.*;
> {code}
>  this sql is useful for some users in many scenarios, such as system cleanup during continuous testing;
