[BUG] node2node (HostNetwork is true, service is false scenario) failing on ROSA cluster

Describe the bug
A clear and concise description of what the bug is.
node2node (hostNetwork is true, service is false scenario) is failing in "ROSA" cluster with below error (k8s-netperf version is v0.1.15). This is not reproducible on self-managed AWS cluster.

To Reproduce
Steps to reproduce the behavior:

1. Run k8s-netperf on ROSA cluster with --all flag (i.e testing hostnetwork)

Similar failure in one of the PROW GCP runs: https://gcsweb-ci.apps.ci.l2s4.p1.openshiftapps.com/gcs/origin-ci-test/logs/periodic-ci-openshift-qe-ocp-qe-perfscale-ci-main-gcp-4.13-nightly-x86-perfscale-gcp-data-path-6nodes-periodic/1711252433637740544/artifacts/perfscale-gcp-data-path-6nodes-periodic/openshift-qe-network-perf/build-log.txt

Also this error started appearing only after this PR: #109. Before this all the jobs were running successfully.

#109 corrected the behaviour of node2node. Prior to this PR, node2node test was actually executng node2pod scenario.
After adding AWS security group which allows port 12865 on AWS workers, netperf client is able to reach the network server.
We need to enhance our perf scripts to enable port 12865 on ROSA AWS workers before running netperf.
