Grafana 9.2 release: Grafana panel help, Grafana oauth updates, Grafana Loki variable editor improvements

Grafana 9.2 introduces a variety of updates and new features designed to enhance dashboard creation and user support, including a new panel help option that streamlines issue reporting and troubleshooting through a wizard that generates data snapshots for support teams. The release also debuts the Canvas panel in beta, allowing users to design custom visualizations with static and dynamic layouts, and simplifies the query variable editor for Grafana Loki to ease variable creation. Improvements to the Google Cloud Monitoring UI provide a more intuitive query-building experience, while transformations now support both INNER and OUTER JOINS for clearer data visualization. Alert rules have been updated to default to an Error state on execution failure, and Grafana 9.2 enhances authentication and authorization by allowing role assignment through Terraform and improved single sign-on capabilities. The update also includes UI enhancements like a role picker for team creation and the ability to organize custom roles into groups, facilitating efficient role management.
