Due to the removal of injection and syncSegments from the compaction, we need to ensure that no compaction is successfully executed during the rolling upgrade. This PR renames Compaction to CompactionV2, with the following effects: - New datacoord + old datanode: Utilizes the CompactionV2 interface, resulting in the datanode error "CompactionV2 not implemented," causing compaction to fail; - Old datacoord + new datanode: Utilizes the CompactionV1 interface, resulting in the datanode error "CompactionV1 not implemented," causing compaction to fail. issue: https://github.com/milvus-io/milvus/issues/32809 Signed-off-by: bigsheeper <yihao.dai@zilliz.com>
