Logstash 8.9.0 Release Notes

Fixed an issue where installs and updates of certain Logstash plugins could fail when located behind a proxy #15131. This issue surfaced after logstash-filter-translate was updated to require that the jar-dependencies gem be used to retrieve artifacts from maven when the plugin was installed. This requirement could prevent the plugin update when a proxy was in use.
Improved logging when Logstash is stalled on shutdown #15056. We now provide additional information about the main thread if it is causing the shutdown to stall.
Improved SSL settings for connection to Elasticsearch for central management and monitoring #15045. This commit adds settings support for file-based certificates and cipher suites for management and monitoring settings, and removes the deprecation warnings from the logs that have been in since SSL configuration settings were revamped in the Elasticsearch output.
