First look feedback

[jpauwels]

Hi, I saw your post on Reddit and decided to give your project a try. I'm familiar with OpenFaaS and exploring alternatives too. I though I'd give some feedback from someone who comes to the project with fresh eyes. Overall it looks promising, but I think a couple of small tweaks could be made to improve the experience of first timers.

Rather than writing long text about it, I decided to propose some minor changes in this PR. They range from essential to suggestions how I'd do it. Don't feel obliged to accept all suggestions, but in order of importance they are:

1. Fixing a missing role permission
2. Remove unnecessary exposed ports
3. Replace namespace creation and setting by kubectl commands with manifest definitions
4. Reorganise the manifests such that it becomes easy to use an Ingress instead of a NodePort to expose SlimFaaS

Next, I'd like to get some more info on how to create and deploy SlimFaaS compatible images, ideally with an example deployment of an OpenFaaS image.

Best wishes, Johan
