Integration with Istio Sidecar

[jdamato-mitre]

What did you do?
Attempted to setup a single cassandra single node cluster with istio-injection enabled.

helm repo add k8ssandra https://helm.k8ssandra.io/stable
helm repo add jetstack https://charts.jetstack.io
helm repo update
kubectl create ns cert-manager
helm install cert-manager jetstack/cert-manager --namespace cert-manager --set installCRDs=true
kubectl create ns k8ssandra-operator
kubectl label namespace k8ssandra-operator istio-injection=enabled --overwrite
helm install k8ssandra-operator k8ssandra/k8ssandra-operator -n k8ssandra-operator --version 1.13.0
kubectl apply --wait -f k8ssandra.yaml

The error occurs when creating the K8ssandraCluster.

Error from server (InternalError): error when creating "k8ssandra.yaml": Internal error occurred: failed calling webhook "vk8ssandracluster.kb.io": failed to call webhook: Post "https://k8ssandra-operator-webhook-service.k8ssandra-operator.svc:443/validate-k8ssandra-io-v1alpha1-k8ssandracluster?timeout=10s": tls: failed to verify certificate: x509: certificate is not valid for any names, but wanted to match k8ssandra-operator-webhook-service.k8ssandra-operator.svc
