Adjust the cost_per_unit for Shard() in SparseFeatureCrossOp to reduce Context
overhead for work where few crosses are created. Document the cost_per_unit
argument of Shard() to mention the impact of passing an incorrect estimate.
Without this fix, Shard()/eigen's ParallelFor splits the work into shards of size 1.

Add optional max_parallelism parameter to tensorflow::ThreadPool::ParallelFor, such that limits on number of tasks provided to work sharder can be respected.
Adds a rudimentary unit test for ParallelFor.

tensorflow: finer-grained Shard parallelization
Provide finer-grained Shard parallelization for the new non-blocking thread pool.
This significantly resembles the parallel for algorithm in eigen executors:
we choose a good block size based on amount of work and parallel efficiency,
and then use recursive division in halves.
