HADOOP-17023. Tune S3AFileSystem.listStatus() (#2257)
S3AFileSystem.listStatus() is optimized for invocations where the path supplied is a non-empty directory. The number of S3 requests is significantly reduced, saving time, money, and reducing the risk of S3 throttling. Contributed by Mukund Thakur. Change-Id: I7cc5f87aa16a4819e245e0fbd2aad226bd500f3f
