Running locally

I've set up convenience recipes for setting up the cluster locally, so after you make sure you've got the submodules and the cluster is up,

git submodule update --init # If you didn't clone --recursive.
minikube start

you can just run these (see Makefile for the full commands):

To spin up the production environment:
```
make test-app-db test-app-backend test-app-frontend namespace=prd
```
- You can run the same with namespace=dev to set up the dev environment.
- It'll use the master branch from the modules as well, but CI uses dev.
- Ideally I'd use Argo or Flux for mapping master/dev -> prod/dev.
To spin up monitoring:
```
make loki kube-prometheus-stack
```
- Default grafana pass is 'prom-operator'.
To spin up the CI runner:
```
make gitlab-runner
```
