Replace ovsfw tempest job with iptables-hybrid tempest job

In commit [1] openvswitch firewall driver is switched to be
default one used in devstack.
So various tempest jobs will use this driver and it will be
tested.
We now need separate job to test non-default firewall driver
which currently is iptables-hybrid driver.
