Perhaps perform a query before and after to confirm the change in behavior.

it's not apparent, but this line waits until /ready returns 200:

added a comment to help clarify that the /ready point is confirmed to be up before we stop tempo

Do we also want to sleep when there are no requests in flight?

i'm concerned about the complexity about that change. this is a very simple one that will do nearly all of what we want with some config choices in k8s

What this PR does:
Adds a shutdown delay configurable parameter modeled after mimir:
grafana/mimir#3298
After receiving SIGTERM Tempo will drop its readiness handler and wait the configured seconds. In a k8s environment this will allow Tempo to cleanly roll its frontend without dropping queries.
