#145 Follow Up: Explore cluster+registry alternatives

[everettraven]

Follow up after merging #145, context:
Have you seen https://github.com/tilt-dev/ctlptl?

Since we're already tilt-enabled, perhaps this is a reasonable tool to evaluate for our cluster setup purposes, especially since it seems to support setting up image registries that are
simultaneously accessible to the local dev environment and the in-cluster processes.

Can we spend 30 minutes now (but time boxed) evaluating this to see if it would be a drop in replacement?

If it is a good candidate, it would be fine to integrate in a follow-up.
