To implement distributed sharing of the KV Cache, it is necessary to first share the block meta information of the KV Cache. This commit implements the classes DistributedRadixTree and LocalRadixTree, which can be used to realize shared KV Cache between CPU and SSD, as well as distributed sharing of PCFS KV block meta information. Based on DistributedRadixTree and LocalRadixTree, this commit also implements a Python wrapper, PCFSCacheEngine, for distributed sharing in PCFS. The CacheEngine implementations for CPU and SSD can also refer to PCFSCacheEngine.
