Use VM on external network in DVR ingress test
In case proxy host on the environment for some reason does not have routing to the external network spawn a VM on external network to use it as a proxy host for sending traffic to the VM under test. Note: on podified environment we can not ping VM in DVR test from a local ip since tempest is running on one of the OCP cluster nodes and FIP-related traffic will be captured on the gateway node (when only compute nodes are expected) and thus affecting the results.
