ovs: Change default bridge names

Default names of OVS bridges used by vsperf were changed
to avoid accidental collision with 3rd party bridges
(e.g. linux bridges) already configured at DUT.
Step driven testcases, which extend existing deployment
scenarios, were updated to use appropriate configuration
options instead of hardcoded bridge names.
