Fix ingress prefix

[bdalpe]

AWS does not support wildcards in the path

[bieron]

@bdalpe are you sure this is true? https://www.stacksimplify.com/aws-eks/aws-alb-ingress/kubernetes-aws-alb-ingress-context-path-based-routing/#step-04-create-alb-ingress-context-path-based-routing-kubernetes-manifest has an example with wildcards, even one that's exactly /*

spec:
  rules:
    - http:
        paths:
          - path: /app1/*
            backend:
              serviceName: app1-nginx-nodeport-service
              servicePort: 80                        
          - path: /app2/*
            backend:
              serviceName: app2-nginx-nodeport-service
              servicePort: 80            
          - path: /*

Just tested on AWS with the EKS ALB Controller and received an error:

Failed build model due to ingress: default/cribl-ldr-leader: prefix path shouldn't contain wildcards: /*

The official documentation does not show this: https://kubernetes.io/docs/concepts/services-networking/ingress/#examples

@bieron maybe we should make this a variable instead of hard-coding the value?
