Add a base test class that sets up and shares state, fields and helper
methods with a number of unit test classes. The unit tests are broken
up into separate classes to make it a little easier to navigate.
HBaseClient is huge!
Modify the TestNSREs class to use the new base test class
Modify some of the static fields to be protected in HBaseClient so that
unit tests can use them
Stub a generic request instance that implements HBaseRpc for testing
purposes
Add the TestHBaseClient class that contains a number of unit tests
for the HBaseClient class (but there are many more to go)
