Cluster monitoring (elastic#926)

👋 howdy, team! 

This is a process test first PR to contribute to new docs content from
Support 🙂. The main goal was to link [Troubleshooting
ES](https://docs-v3-preview.elastic.dev/elastic/docs-content/tree/main/troubleshoot/elasticsearch)
to
[Monitoring](https://docs-v3-preview.elastic.dev/elastic/docs-content/tree/main/deploy-manage/monitor#logging)
as a common Support recommendation to user, but then I got distracted
fixing a typo and then cross-linking guides. So stopping randomly.

TIA! Stef
