Release v0.18.0 · Kuadrant/authorino

What's Changed

AuthConfig v1beta2 API version became the new default version stored in the cluster database

Important! After upgrading to Authorino v0.18.0, users must migrate all AuthConfig resources to v1beta2 stored in the cluster database by running the following script. This can be done at any time before upgrading to newer versions of Authorino post this one, without downtime or any intrinsic risk of breaking deployments before, during or after the migration.
```
cat << 'EOF' > /tmp/migrate.sh
#!/bin/bash
authconfigs=$(kubectl get authconfigs -A -o custom-columns='NAMESPACE:.metadata.namespace,NAME:.metadata.name' --no-headers)
while IFS=" " read -r namespace name; do
  kubectl get authconfig "$name" -n "$namespace" -o yaml > "/tmp/${name}.${namespace}.authconfig.yaml"
  kubectl apply -f "/tmp/${name}.${namespace}.authconfig.yaml"
done <<< "$authconfigs"
EOF
chmod +x /tmp/migrate.sh
/tmp/migrate.sh
```
