HDFS snapshots is a very important HDFS feature in Hadoop 2. We have to have tests for it.
Add DFS tests to TestCLI
Update TestHDFSCLI to include tests from upstream
These tests have been added to TestDFSCLI; closing this issue.
Snapshots will be integrated into TestCLI (which I'm currently working on).
I am only getting back up to speed so this probably isn't right but hey.
