Add a new option "-storagePolicy" to specify the storage policy. If not specified default policy is used as previous. Thanks!

> HDFS heterogeneous storage allows user to store data blocks to different storage medias according to predefined storage policies. Only 'Default' policy is supported in current TestDFSIO implementation. This is going to add an new option to enable tests of other storage polices.
