Cleanup project

[aledbf]

This PR removes yaml manifests to install an ingress controller, ingress examples, and go code used before godog.

The repository should post an example to run the conformance tests locally and as a container, like

1. Create cluster using Kubernetes v1.19.0-rc.0

cat <<EOF | kind create cluster --config=-
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
  kubeadmConfigPatches:
  - |
    kind: InitConfiguration
    nodeRegistration:
      kubeletExtraArgs:
        node-labels: "ingress-ready=true"
  extraPortMappings:
  - containerPort: 80
    hostPort: 80
    protocol: TCP
  - containerPort: 443
    hostPort: 443
    protocol: TCP
EOF

2. Install an ingress controller https://kind.sigs.k8s.io/docs/user/ingress - Ambassador, Contour, Ingress NGINX, etc.

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/kind/deploy.yaml

3. Run tests

go test -v

@aledbf The README.md file will require a complete rewrite given the deleted code. Was it your plan to update it in this PR as well?
