Just add the new boundary '400' like the list partition. CarbonData will
auto merge the range list and split the data file(if exist...)

ALTER TABLE [db_name].table_name ADD PARTITION('400')

If you want to add a value less than the max boundary(e.g.  150), then you
should use 'alter table split partition' statement.
You can check 'TestAlterPartitionTable.scala' for more examples.
