Log test class and method name

I think it might be useful to log test class and method names to make more obvious what's going on

for example:

**2014-01-27 10:28:28 - robottelo - DEBUG - Running test TestModel/test_positive_update_({'name': 'dTK4CAAUm0'}, {'new-name': 'MrjCC4QkfQ'})**
2014-01-27 10:28:29 - robottelo - DEBUG - LANG=en_US hammer -v -u admin -p changeme model create --name='dTK4CAAUm0'
2014-01-27 10:28:29 - robottelo - DEBUG - ['Hardware model created\n']
...
**2014-01-27 10:29:48 - robottelo - DEBUG - Running test TestModel/test_create_model_1**
2014-01-27 10:29:49 - robottelo - DEBUG - LANG=en_US hammer -v -u admin -p changeme model create --name='03l01'
2014-01-27 10:29:49 - robottelo - DEBUG - ['Hardware model created\n']
2014-01-27 10:29:55 - robottelo - DEBUG - LANG=en_US hammer -v -u admin -p changeme --output csv model list --search='name="03l01"'
