Description

It is fairly common for users to wish for more advanced log rotation. For example:

• Automatically rotating the logs at time intervals, e.g. at 00:00:00 every Monday
• Automatically rotating the logs when they reach a certain size, e.g. 250MB

Rather than re-implement these features directly in MongoDB, we have chosen instead to implement work that allows us to integrate well with the de-facto standard and ubiquitous system tooling – the logrotate project – which is available on Linux, macOS, and Windows. (See SERVER-18335)

We have documentation on how to do manual rotations using the built-in features here: https://docs.mongodb.com/manual/tutorial/rotate-log-files/ 

We should build on that and demonstrate how those underlying features allow us to easily integrate with LogRotate and show examples of how to implement some common requests for MongoDB log files, such as those noted above.
