Adding kind configuration for NodePort Testing

[cniackz]

Objective:

To test NodePort in our Operator Service, added kind configuration for that.

Reason:

I have some functions I would like to use with different config:

     13 function createcluster() {
     14         kind delete cluster
     15         kind create cluster --config ~/operator/testing/kind-config.yaml
     16 }
