Problem
We removed the chaining for dashboard queries in #24057 but this is causing an increase of queries hitting the concurrency threshold (as to be expected).
Grafana/Loki shows something like close to a thirds of requests that need to retry ultimately failing, either because they retry too fast or when they retry still there is no capacity.
Changes
Increase the maximum number of retries.
