----------------------------------------------------------------------
* I split {{TestObserverNode}} into 3 modules:
*# Main functionality {{TestObserverNode}}
*# Multiple Observers {{TestMultiObserverNode}}
*# Consistency of reads from Observers {{TestConsistentReadsObserver}}
* Made sure that the mini-cluster is spawn off only once per each module
* Moved common methods into {{HATestUtil}} and {{MiniDFSCluster}}
* Corrected implementation in several places
* Also enabled testMsyncSimple(), which was ignored, waiting for HDFS-13880
[~vagarychen], [~csun] please take a look if you can.

> TestObserverNode combines unit tests for ObserverNode. The tests are of
> different types. I propose to split them into separate modules, factor out
> common methods, and optimize it so that it starts and shuts down
> MIniHDFSCluster once for the entire test rather than for individual test
> cases.
