Summary

This PR is a follow-up on #2782

In #2430 a WARNING level message was added when the defined --limit-max-requests limit is reached and the process is restarted.

IMHO this should be an INFO level message, as it doesn't indicate any abnormal or potentially broken behavior, but in fact a 100% normal behavior. Using WARNING level message really pollutes the logs in high traffic servers, and the only way to silence these messages is to filter them in the logger configuration based on the content of the message, which is far from ideal.

This PR only changes the level of the message from WARNING to INFO.
