Based on the RFC:https://github.com/vllm-project/vllm-ascend/issues/5604
This PR is a refactoring of vllm_ascend/distributed, moving all
kv_transfer realtaed codes into a dedicated folder, which has already
been done in vLLM
### Does this PR introduce _any_ user-facing change?

# For disaggregated mode, set is_disaggregated: true, and set the following parameters:
|
|
# Prefiller_index: the hosts index of the node running prefiller
|
|
# Decoder_index: the hosts index of the node running decoder
|
|
# Suppose we have **4 nodes** running a 2P1D setup (2 Prefillers + 1 Decoder):
|
|
# ┌───────────────┬───────────────┬───────────────┬───────────────┐
|
|
# │ node0 │ node1 │ node2 │ node3 │
|
|
# │ Prefiller #1 │ Prefiller #2 │ Decoder │ Decoder │
|
|
# └───────────────┴───────────────┴───────────────┴───────────────┘
|
|
# For the prefiller nodes. the hosts should be node0 and node1
|
|
# For the decoder nodes. we only have 1 decoder node(dp+tp+ep across node2 and node3. Where node3 is running with headless mode)
|
|
# So the prefiller_host_index is [0, 1], and the decoder_host_index is [2]
