Corrected details for the 'configFile' param

Corrected all details related to the 'configFile' parameter. The current documents refer to a .JSON file which does not exist, the script expects a .YAML file (conf_local.yaml' or 'conf_cloud.yaml). 

Corrected the examples to refer to the 'conf_local.yaml' or 'conf_cloud.yaml' files included in this repo.

-The parameter `configFile` is important (and mandatory) because it contains the configuration used for the Pods in Kubernetes. This allow deploying Pods that use your own resources in Azure or any other cloud provider. A configuration file `local.json` is provided which configures Pods to use the infrastructure containers (that is sql server, rabbitmq, redis and mongodb must be deployed also in the k8s).

 The script will build the code and corresponding Docker images, push the later to your registry, and deploy the application to your cluster. You can watch the deployment unfold from the Kubernetes web interface: run `kubectl proxy` and open a browser to [http://localhost:8001/ui](http://localhost:8001/ui)
