      Description of problem:

      When installing any cluster with Assisted-Installer, one of the CP nodes acts as the bootstrap. After the other CP nodes form a full control plane (and run all of the required pods), it then installs itself as a CP node.
      So when installing TNF, a full control plane needs to be formed with just a single CP node (the one that is not the bootstrap) which doesn't happen.

      Version-Release number of selected component (if applicable):

          

      How reproducible:

      Start an installation of a TNF cluster with one of the CP nodes acting as the bootstrap

      Steps to Reproduce:

          1.Start an installation of a TNF cluster with one of the CP nodes acting as the bootstrap
          2.
          3.
          

      Actual results:

      Cluster installation is stuck, the state of the control plane pods on the CP node (not the bootstrap):
      1. The scheduler is running
      2. The etcd pod is running and ready, sometimes it becomes the leader and sometimes it doesn't
      3. The installer pod for kube-controller-manager is failing because a configmap named client-ca is missing in openshift-kube-controller-manager
      4. There's nothing for kube-api, not an installer pod or a static manifest for it

      Expected results:

      Cluster installed successfully
