[Tarantool-patches] [PATCH] feedback_daemon: add synchro replication usage reporting

[Илья Конюхов]

Hi,

Please increment "feedback_version" each time you patch feedback daemon report. You can do it here - https://github.com/tarantool/tarantool/blob/cf6a9c64dea6a4385f3fd4719e44d0d9dc9ffee9/src/box/lua/feedback_daemon.lua#L359
