This min number should it be based on the current memory usage or the configured maximum usage? Do we want both?

I think it should be based on *current* memory usage. E.g. a user might want to spin up a JDG cluster with 10 nodes and later on he realized that this is too much and he wants to scale it down a bit. If we implemented this using the initial (configured or specified by the user) dataset size, the user will never be able to go below the initial number.

> With Kubernetes autoscaling we need to be able to tell what is the minimum amount of nodes necessary for hosting data (probably some sort of size + number of nodes estimation).
