What this PR does:
Currently, in query-frontend, only the range queries are retried. This PR introduces a generic retry in the query-frontend if the request fails downstream. Raising a draft PR to gather some feedback.

Alternative, I've looked at is #5560. But there are some concerns of unnecessarily encoding/decoding the response just for retry.

Which issue(s) this PR fixes:
Fixes #
