This commit should setup kubectl in a way that it downloads a recent
`kubeconfig` from Digitial Ocean with `doctl`. Thus, deployments will
not fail after a kubeconfig has expired.
Since it seems to be the recommended way to install `doctl` through
[Snap](https://snapcraft.io/). I decided to install everything else
through snap too, including chrome and docker.
The documentation clearly says:
```
Note: A Deployment’s rollout is triggered if and only if the
Deployment’s pod template (that is, .spec.template) is changed, for
example if the labels or container images of the template are updated.
Other updates, such as scaling the Deployment, do not trigger a
rollout.
```
