This patch allows to optionally build the koolbox container on install
if it isn't already present on the system. This should make the usage as
part of the uplevel CLI easier.

Terraform leaves timestamp-based tfstate backups in the terraform
directory, which don't need to remain after a destroy. This patch fixes
the problem by adding the remaining files to the cleanup command ran
after `terraform destory`.

With nginx-ingress in place (or any other ingress-controller), this
patch provides the required DNS entires that can be used directly or as
part of a CNAME entry.

This patch adjust the label selectors for the loadbalancer and splits
into the expected ingress and master labels to correspond with the
firewall rules.

This reverts commit d1106014.

This reverts commit 8701a6ee.

This patch should add utils like `watch` but also basic network tools
like ping to the koolbox container, making it a lot more useful.

After being super frustrated with calico and hetzner firewalls, 
fingers crossed that his will hold up. This patch introduces cilium to
the gitops repository, sets up the firewall rules and adds the CLI to
koolbox.

I spend way too much time on debugging calico in various areas. It seems
like something is borken with the firewall and only when I disable it
completely, it'll work. This is not practical and also not acceptable.

The hetzner terraform module for firewall has a description field added.
This should result in description not just being in terraform as
comment, but as description also in the firewall rules themselves on the
webinterface.
