EKS deployment does not accept https requests, only http

## Steps to reproduce the issue
1. Create EKS cluster: `eksctl create cluster --name test-cluster-1 --region eu-central-1 --node-type t2.large --nodes 1`
2. Label nodes: `kubectl label nodes --all openwhisk-role=invoker`
3. Install Helm chart: `helm install owdev openwhisk-deploy-kube/helm/openwhisk -n openwhisk --create-namespace -f mycluster.yaml`
4. Setup WSK CLI as the [docs ](https://github.com/apache/openwhisk-deploy-kube#configure-the-wsk-cli) say, using the load balancer's DNS: `wsk -i property set --apihost https://:443`
5. Run WSK command: `wsk list -v`

## Observations
* Output of `wsk list -v`:
* Load balancer's info from AWS Console:
* Api calls work when setting up the WSK CLI using http instead of https.

### mycluster.yaml
```yaml
k8s:
persistence:
enabled: false

whisk:
ingress:
type: LoadBalancer
annotations:
service.beta.kubernetes.io/aws-load-balancer-internal: 0.0.0.0/0
service.beta.kubernetes.io/aws-load-balancer-ssl-cert: arn:aws:iam::XXXXXXXXXXXX:server-certificate/ow-self-signed

whisk:
ingress:
awsSSL: "true"
type: LoadBalancer
annotations:
service.beta.kubernetes.io/aws-load-balancer-backend-protocol: http
service.beta.kubernetes.io/aws-load-balancer-ssl-ports: https-api
service.beta.kubernetes.io/aws-load-balancer-ssl-cert: arn:aws:acm:eu-central-1:XXXXXXXXXXXX:certificate/YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY # AWS Certificate Manager (ow-self-signed).
```

## Reason of interest
I want to use the OpenWhisk deployment as an endpoint for *AWS EventBridge*, but currently it is only possible to add *API Destinations* that use https endpoints.

The payload names no repository files or tests. Start by reproducing the issue with the listed eksctl, Helm, and WSK commands, then inspect the Helm ingress configuration and AWS LoadBalancer annotations shown in mycluster.yaml. Done means the deployed EKS endpoint accepts the WSK CLI request over HTTPS as well as HTTP.
