This class aims to mark the {@link PlanNode} of schema operation assigned by configNode to
selectively forward the operations, {@link Statement}s of which extending {@link
IConfigStatement}. The handling logic is defined only in {@link SchemaExecutionVisitor} to
execute deletion logic and mark it as received, since the request is assigned directly to {@link
RegionWriteExecutor} and needn't be split by partition.

<p>

<p>Notes: The contents includes all the collected {@link PlanNode}s of schema deletion:

<p>- Timeseries: {@link DeleteTimeSeriesNode}

<p>- Template: {@link DeactivateTemplateNode}

<p>- LogicalView: {@link AlterLogicalViewNode}, {@link DeleteLogicalViewNode}

<p>Intermediate nodes like {@link ConstructSchemaBlackListNode} will not be included since they
will not be collected by pipe.
