Attaching v001 patch to address license and checkstyle issues.
Looked through the test failures and it seems they are OOM-related due to not
enough native threads, related to new enforcement from HDFS-12711

> Currently {{SimulatedFSDataset}} (and thus, {{DataNodeCluster}} with
> {{-simulated}}) only supports a single storage per {{DataNode}}. Given that
> the number of storages can have important implications on the performance of
> block report processing, it would be useful for these classes to support a
> multiple storage configuration.
