    Add cluster-host unit IP to apiserver cert SANs

    When OAM IP changes, platform::kubernetes::certsans::runtime class in
    kubernetes.pp is applied. The runtime puppet class will update
    apiserver's certificate among other configuration updates. However
    the cluster-host unit IP address is missing from the cert's SAN list
    after the update on SX system.

    This change fixed the issue by adding cluster-host unit IP address back
    to apiserver cert's SAN list for SX system.

    Test Plan:
    PASS: On a AIO-SX system, run "system oam-modify oam_ip=<new IP>" to
          change its OAM IP address. Verify controller's cluster-host unit
          IP address is in the cert's SAN list after OAM IP address has
          been changed.
