If there almost always are vehicles and predictions, what happens in the rare times when there aren’t? Can we run this in a dev environment for a while? |

Summary of changes
Asana Ticket: ad-hoc
Problem:
During the incident on 10/21 in which the API stopped returning vehicles, we allowed API instances to become healthy with no vehicles. I also noticed that we allow API instances to become healthy with no predictions, whereas there are almost always predictions and vehicles in the API... even at 3AM.
Solution:
Add vehicles and predictions to the API's health check so that new instances with no vehicles cannot join the ALB
