This commit adds a new parameter called password_expiration_warning_threshold that controls when the server begins emitting imminent-password-expiration warnings upon successful password authentication. By default, this parameter is set to 7 days, but this functionality can be disabled by setting it to 0. This patch also introduces a new "connection warning" infrastructure that can be reused elsewhere. For example, we may want to warn about the use of MD5 passwords for a couple of releases before removing MD5 password support.
