ARROW-1352: [Integration] Added specific formatting for producer consumer output

Changed output of integration tests to give a specific format when indicating producer/consumer.  The new output will look like this:

```
-- Creating binary inputs
-- Validating file
-- Validating stream
##########################################################
Java producing, C++ consuming
##########################################################
==========================================================
Testing file /home/bryan/git/arrow/integration/data/struct_example.json

-- Validating stream
```
