Installation OKD 4.15

Following indications in the reference "Installing single-node OpenShift on AWS".

The minimum resource requirements for high availability cluster installation include a control plane node with 4 vCPUs and 100GB of storage. For a single-node OKD cluster, you must have a minimum of 8 vCPU cores and 120GB of storage.

The controlPlane.replicas setting in the install-config.yaml file should be set to 1.

The compute.replicas setting in the install-config.yaml file should be set to 0. This makes the control plane node schedulable.
