Change configurator to use separate app
I created a separate, prototypical service for the analytics-configurator to make it easier to work with the code to setup Clickhouse for Snowplow/Kafka in Kubernetes.
This MR changes the setup to use the service instead of the Rake tasks.
How to test
Follow the readme section for setting up a new project with Snowplow.
