Instead of being strongly tied to unittest2 make it easier for taskflow to switch to another root class (testr?) by abstracting out the unittest2 usage. This also enables some useful functionality to exist in that root test class that other tasks can take advantage of. Change-Id: I381b6fb07e47f984b44cde439a17f39a1c1d32ac
