Create a followup task for dealing with jobs which access multiple tables.
For that, we need to associate the index formats/files with specific tables,
and that requires modifying the way the index input format works.

<https://reviews.apache.org/r/558/#comment1105>
Create a followup task for displaying these in the plan (to indicate that a
table scan's input is being filtered by the intermediate file). We only want
to do that when they are non-null (to avoid upsetting all the existing test
reference files).

When logging errors being propagated, use the two-arg version of the method
and pass e as the second arg. Same thing in a few other places.

create a followup for this one

This is not an error, just a condition that prevents usage of the index, so
it should be logged as info rather than error.
