When trying to install cluster with static IPs, control plane nodes are recreated by CPMS and the IPs is no longer static, details see https://redhat-internal.slack.com/archives/CH06KMDRV/p1706255642178569

    4.15.0-0.nightly-2024-01-22-160236

    always

    1. install cluster with static IPs defined
    2. check control plane nodes IPs     

    control plane nodes are reconciled by CPMS and the IPs is no longer static

    control plane nodes should use static IPs defined

    There are some differences in manifest, maybe that's the reason why CPMS recreated master nodes
