Ethan Feng b7f9b6ab27 [Metrics] Add group-aware KV cache capacity to vllm:cache_config_info (#42206) 
The startup log already reports the correct group-aware KV cache capacity for
hybrid models, but Prometheus did not expose matching info in 'vllm:cache_config_info`.

This PR adds kv_cache_size_tokens and kv_cache_max_concurrency.
