This PR adopt `LLMDataDist` for kv cache register and `pull_blocks` style disaggregate prefill implementation.

This PR can be test with the following step: - Generate the rank table for all machine. - execute`toy_proxy.py` to launch the disaggregate prefill proxy server, specify the prefill ip, port and the decode ip, port - Run the prefill server and decode server. - send the request to the disaggregate prefill proxy ### Does this PR introduce _any_ user-facing change? ### How was this patch tested? - vLLM version: v0.9.2 - vLLM main: https://github.com/vllm-project/vllm/commit/8d0a01a5f2b53794e4bc6b734d7b63cb8a9b7d7d --------- Signed-off-by: ganyi <pleaplusone.gy@gmail.com> Signed-off-by: machenglong <machenglong_yewu@cmss.chinamobile.com> Signed-off-by: liziyu179 <3475441767@qq.com> Signed-off-by: underfitc <hucong24@huawei.com> Signed-off-by: zouyida2052 <zouyida@huawei.com> Signed-off-by: liziyu <liziyu16@huawei.com> Signed-off-by: underfituu <hzhucong@163.com> Co-authored-by: machenglong <machenglong_yewu@cmss.chinamobile.com> Co-authored-by: liziyu179 <3475441767@qq.com> Co-authored-by: underfitc <hucong24@huawei.com> Co-authored-by: zouyida2052 <zouyida@huawei.com> Co-authored-by: liziyu <liziyu16@huawei.com> Co-authored-by: underfituu <hzhucong@163.com>
