This PR introduces support for Redis COMMAND-based request_policy and response_policy routing for Redis commands when used in OSS Cluster client.
Key Additions:
Command Policy Loader: Parses and caches COMMAND metadata with routing/aggregation tips on first use.
Routing Engine Enhancements:
Implements support for all request policies: default(keyless), default(hashslot), all_shards, all_nodes, multi_shard, and special.
Response Aggregator: Combines multi-shard replies based on response_policy:
all_succeeded, one_succeeded, agg_sum, special, etc.
Includes custom handling for special commands like FT.CURSOR.
Raw Command Support: Policies are enforced on Client.Do(ctx, args...).
