  - reclass: pod_config: Revert MaaS IPs to .3

    PDF compatible reclass support moved the MaaS IPs from .2 to .3.
    However, the runtime template was not updated accordingly, leading
    to mismatches between IP addresses. Until all scenarios support
    pod_config, we can't apply the IP change correctly, so revert it.
