Create a simple program for deploying ETOS to Kind for local testing

Applicable Issues

Description of the Change

This change creates a program for deploying a local ETOS cluster on an existing kind cluster. It is very similar to how we deploy ETOS when running e2e tests. This deployment should be used to test changes locally before sending a PR.
The program has a few Packs which can return a set of Commands that should be run to deploy that Pack. The name Pack is not that descriptive but I struggled to find a better name for a collection of commands to deploy and verify a set of resources.
Then we just execute the commands in the order they are defined to deploy ETOS properly. At the end we also run a quick verification that the cluster works by running a TestRun in the new cluster.

The cluster be deployed using make deploy-local and undeployed using undeploy-local
The cluster will not work with the etos client at the moment since we do not deploy an ingress (and deploying an ingress would make everything much more complex).
It is still possible to create TestRun resources directly to the cluster which allows us to test ETOS locally.

Alternate Designs

We could add this to etosctl to make it more available, but it would require the makefile to install etos client which I wanted to avoid for now. Currently we have no external python dependencies with this program.

Possible Drawbacks

There are a few things here that we should investigate.
The program assumes that the config/samples work and don't change too much.
It hard codes versions for cert-manager and prometheus.
It uses the config/samples/*cluster.yaml file which does not get updated image versions.

All of these problems should be fixed and I will write issues for them after I've merged this PR.
