adding init

[robinmordasiewicz]

Adds initialization steps to improve the setup and configuration of our infrastructure. In the kustomization.yaml file, the flannel resource has been removed and the fortiweb-ingress resource has been added.

In the spoke-k8s_cluster.tf file, the following changes have been made:

• support_plan has been set to "AKSLongTermSupport".
• kubernetes_version has been updated to "1.27".
• sku_tier has been changed to "Premium".
• The network_plugin has been modified to use "azure".
• The pod_cidr setting has been commented out for future reference.

These changes aim to enhance the initialization process and ensure a more robust and efficient setup for our infrastructure.
