Circleci project setup

[DrPsychick]

BC break! jobs is now a "dict", so you can access variables via name: helm --set jobs.job1.env[0].value=...

Challenges:

• use aliases for steps and "merge" list or dict -> did not work
  • => use one job with all steps defined
• use docker with --volume to run ct -> does not work with remote-docker
  • => install and run ct locally (only needed a few more dependencies...)
• run CI with different values.yaml than the chart -> works!
  • see https://github.com/helm/charts/blob/master/test/README.md#providing-custom-test-values
• talk to kind k8s cluster on remote-docker -> works!
  • installed socat and port-forward via pipe to control-plane docker, inspired by: https://github.com/tilt-dev/kind-local
