Summary: Shard tests to support parallelism across multiple machines

Description:
Shards tests based on a hash of their test name enabling easy parallelism
across machines, suitable for a wide variety of continuous integration
services. Tests are split at the finest level of granularity, individual test
cases, enabling parallelism even if all of your tests are in a single file (or
even single parameterized test method).
