Description

The Jetty request logs (NCSA format, typically) are currently configured for 90 day retention.
https://www.eclipse.org/jetty/documentation/current/configuring-jetty-request-logs.html
solr/server/etc/jetty-requestlog.xml This file is partially redundant with Solr's Log4j2 based logging, but it has unique information useful for diagnosing a security breach or for seeing which of the clients in your environment are talking with Solr. Let's dial this down to 7 days, or even less (3?).

BTW our Log4j2 logs are rotated by file size, not time.
