Triple-quote string values in HOCON config files no longer support escape sequence.

The detailed information can be found in this pull request. Here is a summary for the impact on EMQX users:

  • EMQX 5.6 is the first version to generate triple-quote strings in cluster.hocon, meaning for generated configs, there is no compatibility issue.
  • For user hand-crafted configs (such as emqx.conf) a thorough review is needed to inspect if escape sequences are used (such as \n, \r, \t and \\), if yes, such strings should be changed to regular quotes (one pair of ") instead of triple-quotes.
