This commit adds a logic to cache `CLUSTER SLOTS` response for reduced latency and also updates the cache when a change in the cluster is detected. Historically, `CLUSTER SLOTS` command was deprecated, however all the server clients have been using `CLUSTER SLOTS` and have not migrated to `CLUSTER SHARDS`. In future this logic can be added to any other commands to improve the performance of the engine. --------- Signed-off-by: Roshan Khatri <rvkhatri@amazon.com>
