doc: Clarify the logging collector's guarantees. Presently, the documentation for logging_collector says that the collector "is designed to never lose messages," which reads as a stronger promise than we actually make. The collector does not fsync the log file or retry failed writes, so log messages can go missing after an operating system crash, power loss, or a write error. Reword that sentence and add a note about what is not guaranteed.
