> In old version, pipe infomation will be stored even if pipe has been dropped. There are two advantages to not storing pipe infomation after drop can.
>  # Support rollback logic in procedure better. If failed to create pipe, drop directlt.
>  # Other modules(e.g.Trigger) do the same thing. Doing so can keep the semantics consistent in IoTDB.
