telco5g: Detect and set SRIOV enabled interfaces for tests

[sshnaidm]

This PR updates the telco5g CNF test step in the openshift/release CI to automatically discover and set SR-IOV-capable interfaces on test nodes so e2e tests only target compatible devices.

What changed (practical impact)

• The telco5g CNF test command script (ci-operator/step-registry/telco5g/cnf/tests/telco5g-cnf-tests-commands.sh) now runs a pre-test discovery on each test node using oc debug to inspect host paths (/sys/class/net/*/device/sriov_totalvfs).
• Interfaces with sriov_totalvfs > 0 are collected and formatted as "node:interface" entries, joined with pipe (|) delimiters.
• When any SR-IOV-capable interfaces are found, the script exports SRIOV_NODE_AND_DEVICE_NAME_FILTER with that value so downstream e2e tests are constrained to those node:device pairs.
• If discovery fails or finds no interfaces the script logs a warning and continues without setting the filter (tests remain runnable on environments without SR-IOV hardware).

Why this matters for CI

• Makes telco5g CNF CI jobs in openshift/release hardware-aware and adaptive: tests automatically target available SR-IOV devices without static configuration changes.
• Reduces false negatives and manual configuration when running CNF SR-IOV tests across heterogeneous or dynamic lab/hardware environments.

Exports/Side-effects

• Conditionally exports SRIOV_NODE_AND_DEVICE_NAME_FILTER when SR-IOV-capable interfaces are detected.

Walkthrough

Adds a pre-test SR-IOV interface discovery step that runs oc debug on each test node, reads /sys/class/net/*/device/sriov_totalvfs from the host filesystem to find interfaces with sriov_totalvfs > 0, and conditionally exports a pipe-separated SRIOV_NODE_AND_DEVICE_NAME_FILTER of node:interface entries.

Test Structure And Quality	✅ Passed	This PR modifies a bash shell script, not Ginkgo test code. The custom check for Ginkgo test quality is not applicable.
Microshift Test Compatibility	✅ Passed	PR does not add Ginkgo e2e tests. Only modifies shell script for SR-IOV interface discovery and environment setup. Custom check is not applicable.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	PR does not add new Ginkgo e2e tests. The file is a bash CI orchestration script that discovers SR-IOV interfaces. The custom check is not applicable.
Topology-Aware Scheduling Compatibility	✅ Passed	PR adds a CI test shell script that discovers SR-IOV interfaces. Not a deployment manifest or operator code - does not introduce scheduling constraints. Check not applicable.
