It's too hard

I don't know how else to put it - setting up gitkube is way too hard, please make it easier.

In the install guide
```
kubectl create -f https://storage.googleapis.com/gitkube/gitkube-setup-stable.yaml
```
this yaml still causes errors, even though this seems to have been merged https://github.com/hasura/gitkube/commit/416c8d708be79df3f504279d2ab671f634565a5d

```
$ kubectl --namespace kube-system expose deployment gitkubed --type=LoadBalancer --name=gitkubed
```
LoadBalancers cost at least $10/month. Those who are using gitkube are probably looking for low-cost options. I recommend using ingress or nodeport here.

There are namespace concerns. Gitkub seems like a good candidate for using the kube-system namespace but sometimes apps need to live in different namespaces. Is that possible?

`gitkube.sh` doesn't mention a cli anywhere. If there is a cli, then why are all these manual steps required?

Start with the install guide, gitkube-setup-stable.yaml, and gitkube.sh, then reproduce the documented kubectl commands and their errors. Review the concerns about LoadBalancer cost, ingress or NodePort, namespace selection, and the CLI workflow. Done should mean a clearer, working installation path with the requested deployment and namespace options documented or supported.
