Make managed dependecy optional

[bhack]

Use case
With the managed option I want to have some components excluded (e.g. minikube)

Feature
I think it could often happen that you could not need minikube if you are working on GKE without it isrequired to switch to the unmanaged setup.

Thanks for the request! Managed dependencies at this point is a convenience option that we are looking to reduce the usage for. We have no plans to develop the feature further.

So what alternative are you planning to the managed dependencies?
