Address review feedback and adjust test to more accurately test the upgrade
scenario.
# we now corrupt all 2NN directories
# we now test upgrade from -39 which fixes some unexplained test failures
# clean up the test
# drop the datanodes and use mkdir instead of writefile for quicker test
startup.

> The error check we're hitting came from HDFS-1073, and it's intended to
> verify that we're connecting to the correct NN. But the check is too strict
> and considers "different metadata version" to be the same as "different
> clusterID".
> I believe the check in {{doCheckpoint}} simply needs to explicitly check for
> and handle the update case.
