Dummyhttp kustomize application

This application deploys a container that runs an instance of the dummyhttp application that returns a string that uses environment variables added to the container from a ConfigMap and a Secret.

The container image is built from a generic Dockerfile that runs the application directly, but we have modified the arguments on the Deployment to be able to use environment variables on the arguments to the server (we use /bin/sh -c as entrypoint and the command uses eval to expand the environment variables when calling the application).

The base application includes a Deployment, a Service and an Ingress definition; the Deployment uses environment variables from a ConfigMap and a Secret if they are available, but we've marked them as optional to be able to deploy the application without having them available.
