This adds support for asynchronous logging, so that log attempts are not blocking. Further (and most important), this adds a
Flush()
method, which can be used to ensure that any queued log messages are sent.This functionality is heavily influenced by the async operation of the logrus-graylog plugin.
Without this functionality, there is no way to ensure that all logs have been sent when the program exits, possibly leading to the final log(s) being lost when a program exits or crashes.
