[FLINK-6039] [core] Row of TableFunction should support flexible number of
fields
Type: Improvement
Priority: Major
Components: core, table, udtf
Problem Definition: Row of TableFunction should support flexible number of
fields. The number of fields should not be fixed. The framework should allow
the scenario that the field numbers of the `Row`s are different from the
`TypeInformation` number of the `ResultType`s.
Design:
It would throw a IndexOutOfBoundException when accessing the position
larger than or equal to the number of fields in a Row, before the patch. It
will return null after the patch.
Impact Analysis:
The behavior of the Row#getField has changed.
Test:
`mvn clean verify` is done.
The case `TableFunc4` and `TableFunc6` would pass no matter this patch is
patched or not. They are here to make sure the case works.
The case `TableFunc5` would success after the patch is patched.
