Frontend: Retry failed request.

Right now if a queries fails in the query frontend we actually fails everything, we should at least retry like Mimir and Loki.

This is the downstream middleware they use https://github.com/grafana/loki/blob/main/pkg/querier/queryrange/queryrangebase/retry.go

We should have the same middleware too with a good default config for any downstream queries from the frontend.

To learn more about the query frontend see https://grafana.com/docs/mimir/latest/references/architecture/components/query-frontend/

@bryanhuhta A good one to learn about the query-frontend.
