Review comment:
`FromElementsFunction` relies on feature that
`AbstractUdfStreamOperator` will redirect `OutputTypeConfigurable` to its
function. But `StreamGraphGeneratorTest` does not have test for this while it
has tests for
`StreamOperator`(`testOutputTypeConfigurationWithOneInputTransformation` and
`testOutputTypeConfigurationWithTwoInputTransformation`). This test resides in
a separate commit.
