Replace and remove LOG_MSG

`LOG_MSG` is legacy code from Ignite. Since now we have different log levels, we should replace calls of `LOG_MSG` with `LOG__MSG`. There are less than or equal to 85 `LOG_MSG` calls

AC:

- remove all calls to LOG_MSG
- remove LOG_MSG definition in log.h
- look at `LOG_MSG` calls case by case, and decide if it should be converted to one of: `LOG_DEBUG_MSG`, `LOG_INFO_MSG`, or `LOG_ERROR_MSG`.

Search the repository for all LOG_MSG calls, then read log.h to inspect the LOG_MSG definition. Review each call in context and classify it as debug, info, or error. Done means no LOG_MSG calls remain and the LOG_MSG definition has been removed from log.h.
