/*
We use a different RMAPS_MAP_INSTANCE_NAME for each staging/dev instance,
that way we can avoid duplicate apps in the APM manager
of New Relic -- otherwise this would become a maintenance hell.

Developers should limit their staging to 1 Dyno of the smallest size to keep cost down, especially when new relic is
pinging the app (which will keep it from sleeping).

Maintenance:
  FYI to delete an app from new relic, you need to have OWNER heroku privileges and the Heroku app must be shut down
  it takes a few minutes for New Relic to decide that it is down (GREYED out)
