Provide builder for constructing instances of MiniDFSCluster
------------------------------------------------------------

                 Key: HDFS-1456
                 URL: https://issues.apache.org/jira/browse/HDFS-1456
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: test
    Affects Versions: 0.22.0
            Reporter: Jakob Homan
            Assignee: Jakob Homan
             Fix For: 0.22.0


Time to fix a broken window. Of the 293 occurences of "new MiniDFSCluster("... most look something
like:
{noformat}cluster = new MiniDFSCluster(0, config, numDatanodes, true, false, true,  null,
null, null, null);{noformat}
The largest constructor takes 10 parameters, and even the overloaded constructors can be difficult
to read as their mainaly nulls or booleans.

We should provide a Builder for constructing MiniDFSClusters to improve readability.
