2. add kv_combine flags to compactor command 3. in class version_edit, we add rollback_ member as a switch to control encode process, and we check the sst' status, if we open the rollback_ switch, we will check the file's prop, like purpose, dependence, inheritance. 4. in class version_set, we add a public method manifestRollback, and we add a rollback param to the WriteSnapshot method.
2. struct SstFileMetaData add terarkdb_file member, the value is true Means the sst is a terarkdb file instead of rocksdb file
