## bugfix/core

* Added decoding of election messages: `RAFT` and `PROMOTE` to
  `xlog` Lua module (gh-6088). Otherwise `tarantoolctl` shows
  plain number in `type`
  ```
  HEADER:
    lsn: 1
    replica_id: 4
    type: 31
    timestamp: 1621541912.4592
  ```
  instead of symbolic representation
  ```
  HEADER:
    lsn: 1
    replica_id: 4
    type: PROMOTE
    timestamp: 1621541912.4592
  ```
