enhancement: report dependency not installed to kuadrant & policy status

[KevFan]

Description

Closes: #730

Report in the Kuadrant and Policy status when required dependencies are not installed

• Kuadrant CR
  • Gateway API not installed
  • Gateway Provider (istio / envoy gateway) not intalled
  • Limitador Operator not installed
  • Authorino Operator not installed
• AuthPolicy CR
  • Gateway API not installed
  • Gateway Provider (istio / envoy gateway) not intalled
  • Authorino Operator not installed
• RateLimitPolicy CR
  • Gateway API not installed
  • Gateway Provider (istio / envoy gateway) not intalled
  • Limitador Operator not installed
• TLSPolicy CR (does not require a Gateway Provider)
  • Gateway API not installed
  • CertManager not installed
• DNSPolicy CR (does not require a Gateway Provider)
  • Gateway API not installed
  • DNS Operator not installed

Verification

• Gateway API and Gateway API provider status are tested by integration tests, so passing integration tests should be enough

To verify other status:

• Create cluster

make local-setup

• Delete CRDs to simulate not installed

# DNS Operator
kubectl delete crd dnsrecords.kuadrant.io   
# Authorino Operator                                                                    
kubectl delete crd authconfigs.authorino.kuadrant.io
kubectl delete crd authorinos.operator.authorino.kuadrant.io
# Limitador Operator
kubectl delete crd limitadors.limitador.kuadrant.io
# Cert Manager
kubectl delete crd certificates.cert-manager.io

• Apply CRs

kubectl apply -f config/samples/kuadrant_v1_authpolicy.yaml                                      
kubectl apply -f config/samples/kuadrant_v1_dnspolicy.yaml
kubectl apply -f config/samples/kuadrant_v1_ratelimitpolicy.yaml
kubectl apply -f config/samples/kuadrant_v1_tlspolicy.yaml
kubectl apply -f config/samples/kuadrant_v1beta1_kuadrant.yaml

• Check status

kubectl get kuadrant kuadrant-sample -o yaml | yq '.status'
kubectl get authpolicy authpolicy-sample -o yaml | yq '.status'
kubectl get ratelimitpolicy ratelimitpolicy-sample -o yaml | yq '.status'
kubectl get dnspolicy dnspolicy-sample -o yaml | yq '.status'
kubectl get tlspolicy tlspolicy-sample -o yaml | yq '.status'
