CI: Add path and namespace configuration for OC CNs

- Modify CN deployment and termination functions to include namespace and path parameters.
- Update `Module_UE` class with new attributes for namespace and CN path.
- Integrate `cnID` for OC CN deployment and termination in `epc.py`.
- Extract `cn_id` from XML configurations for CN operations.
- Update XML files to include `cn_id` tag for 5G Core initialization and
  termination. (Used in OAIUE and AW2S pipeline, for OC CN deployment. This change
will not affect other CN deployments.)
