Recently, we expanded Cockroach Demo to include movr by default as well as allow for creating nodes. We should further expand upon this work to allow for setting of locality via Cockroach Demo.

I'm imagining something like:

./cockroach demo movr --nodes 3 --locality=us-east1-b,us-central1-a, us-west1-a

Where each comma separates a locality.

This will make it easier to simulate and test partitioning and other features.
