Description

PR #12861 introduces two parameters (keepalive_timeout and keepalive_pool) to rate limiting plugins (limit-count, limit-conn, limit-req).

The parameter names, keepalive_timeout and keepalive_pool, are not very consistent with the rest of the Redis related parameters, which are prefixed by redis_.

Additionally, there was a discussion for the ai-rate-limiting plugin to support Redis, and the parameter controlling the redis keepalive timeout shall be named redis_keepalive_timeout.

Feature added by #12861 is about to be released with 3.15.0. Given the above considerations, it would be better to rename keepalive_timeout and keepalive_pool to redis_keepalive_timeout and redis_keepalive_pool before the release for improved clarity and to prevent a future breaking change.
