Currently test classes in zaqarclient/tests/queues/flavor.py contain
class variables:
url = 'http://127.0.0.1:8888/v1.1'
version = 1.1
These class variables should be only defined in child classes of the
classes defined in flavors.py.
This parch removes class variables from flavors.py, because they are
redundant.
