The recent commit I45d73891f3c0829a2378a032dfc02e5ac0ee34b7
deduplicated the base test class methods from the tempest.lib
reintegration. However the surviving base class was put in the wrong
namespace. The base class is just that a base to build the individual
test subclass off of. It's very confusing for that to not live in the
base tests namespace. While the code in lib is supposed to be self
contained there isn't a reason to do that here for the unit tests,
especially because in this case the import heiarchy becomes more
confusing with the base living in a submodule. This commit moves the
base class to the base tempest.tests namespace where it really
belongs.
