Install Kubeflow locally

For local installation of Kubeflow you can use Vagrant box, Minikube or install it using Multipass. Here I will describe the multipass installation.

The deployment will hook wrong image, so cluster won't build without the fix. Problem is in the naming of the image used to build rabbits. image: "${APPLICATION_NAME}:${RABBITMQ_VERSION}" Change to: image: ...
