As a contributor to Greenhouse (core/plugins), I would like to spin up a running local environment with one command, so that I can focus on development/testing.

The localenv should provide a way that the developer (UI, Plugin, Core) just needs one command to spin up a local environment. Parts of this flow can be solved by providing configuration for the localenv via the config json.

Acceptance Criteria

• spin up two KinD clusters
• configure one KinD cluster as the Greenhouse central cluster
• bootstrap demo resources e.g. here, but at least a Demo Organisation
• Onboarding of a single Cluster into the Demo Organisation
• Spin up the Greenhouse Dashboard running against Greenhouse in the KinD cluster
