pwa api rest template

# This consolidated YAML file contains configurations for:
# 1. Calico Installation (Installation and APIServer resources)
# 2. A permissive Egress NetworkPolicy for the 'default' namespace
#
# These are standard Kubernetes resources that can be applied directly using 'kubectl apply'.
# The kubeadm-specific ClusterConfiguration and InitConfiguration have been removed
# as they are only processed by the 'kubeadm init' command, not 'kubectl apply'.

# --- Calico Installation: Base configuration for Calico ---
