  Test Runner: Print reproduction steps on a batch failure.
  
  This prints out a large gtest_filter of the tests in a batch. Makes
  reproducing a particular failure much easier.
  
  In the future we could potentially look at using an encoding to
  reproduce a specific batch: e.g. a flag that acceps a batch / shard
  number and runs those tests based on using the same internal counts.
