Instead of having our own mock subclass that has similar functions as the oslotest base mocking class just use the base class functions where we can and add on our own customizations as we choose to. This change moves to using the base classes fixtures and also adjusts the customized subclass method names to match closer to the rest of the unittest classes method name style (camel-case not underscores).
