Robert Schäfer 2dc5252f38 Install everything on Travis CI through snap
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.
