One of the things users ask when starting to use Testkube is "What's the diference between Tests and scripts" so I was thinking how to improve that.

Any feedback on this? Use emojis do tell me your favourite ideas.

keep in mind that converting will have high cost of refactor - we need to change almost all parts of code from one to another including CRDs, commands, resoruces, api clients, kubernetes clients.
