Tests requiring Kubernetes Cluster are now moved out of
the regular CI tests and moved to "kubernetes_tests" folder
so that they can be run entirely on host without having
the CI image built at all. They use production image
to run the tests on KinD cluster and we add tooling
to start/stop/deploy the application to the KinD cluster
automatically - for both CI testing and local development.
This is a pre-requisite to convert the tests to convert the
tests to use the official Helm Chart and Docker images or
Apache Airflow.
