The default ShardingTest verbosity is currently zero, but we have many tests, which bump it to 1 and even higher. Since verbosity level of 0 is sometimes insufficient for investigating transient failures, this change makes the default to be 1 and removes all places, which explicitly make it 1 or higher.
