[java client] Upgrade hadoop-client to 2.7.2

With the old version, I was hitting HADOOP-10961 when running
kudu-mapreduce:TestOutputFormatJob locally. Now, the test passes. Strange
that this isn't happening in gerrit builds though.

Now we depend on upstream hadoop artifacts now instead of CDH artifacts.
