Description

Now, blink planner use ContinuousFileReaderOperator to support InputFormat, but ContinuousFileReaderOperator not support multiple paths.

If read partitioned source, after partition pruning, we need let InputFormat to read multiple partitions which are multiple paths.

We can use InputFormatSourceFunction directly to support InputFormat.
