This change adds a load property named strict_mode which is used to prohibit the incorrect data.
When it is set to false, the incorrect data will be loaded by NULL just like before.
When it is set to true, the incorrect data which belongs to a column without expr will be filtered.
The strict_mode is supported in broker load v2 now. It will be supported in stream load later.
The non-streaming hint of insert into will use the streamin plan which is same as the plan of stream insert.
It will also record the load info and return the label of insert stmt.
The partition is supportted in insert into stmt. The result which meet the target partitions will be loaded.
The introduction of example has been changed especially non-streaming insert.
Also, the param of partition_names is added in sql syntax which is used to declare the target partition_names in target table.
Change META_VERSION to 50
