Add test_qos.py tests

Moved almost all tests from the downstream test_qos.py except
test_qos_user_policies that was intended for non-RBAC environments.
The test can be handled later in another patch, if needed.

Added window_size parameter for tweaking iperf functionality.

Updated test uuids in order to distinguish between d/s tests.

Changed node to ubuntu (nested-virt-ubuntu-jammy) in order to
overcome node_failure zuul issues with centos-9-stream.
