This PR adds the experimental compiled DAG API support for VLLM NCCL opimization. It improves the benchmark_latency.py or 70B * 8 A100 GPUs' throughput benchmark around 5~7%.
The feature is off by default, and it can be enabled using an env var (VLLM_USE_RAY_COMPILED_DAG=1). There are some rough edges we are fixing within Anyscale, and once we fix them and are more confident, we can turn this on by default.
