/*
Waits for a terminate | interrupt signal, ctrl-c before finishing main

when creating services and adapters, I like to return a cleanup function that is deferred for
each service, thus when the app closes they are teared down in reverse order.

graceful.Exit() returns two functions:

  - waitFor - which is called as the last statement of main. This will block until a signal to terminate or interrupt the executable.
  - deferMe - defer this first before the service cleanups. This ensures thar stdout/err are flushed and sleeps 1 second before exiting.
