feat(response-ratelimiting): add support for secret rotation with redis connection
Summary
Adds support for secret rotation for redis credentials in response-ratelimiting plugin.
@bungle I have seen this PR was added to 3.3 milestones, And the code looks Okay. Why was this PR labeled draft?
Moving this to 3.4, and perhaps abstract it a bit more.
I'm going to remove this from the 3.4 milestone. We are too busy fixing the bugs we found on the "regular" (non-try-based) TTL code to expand the scope even more. Also, this PR has no tests.
I'm approving this because (request-)ratelimiting has the same change and otherwise this would make both plugins iconsistent.
