Breaking changes

Potential failure to start in Ubuntu 18.04 / Debian 9 / CentOS

• In Grafana v8.2.0, this change can prevent the grafana-server service from starting on older versions of systemd, present on Ubuntu 18.04 and slightly older versions of Debian. If running one of those versions, please wait until v8.2.1 is released before upgrading. If you still want to upgrade or have already ugpraded, a simple fix is available here: https://github.com/grafana/grafana/issues/40162#issuecomment-938060240 Issue #38109

Plugin development fixes & changes

• Plugins: Create a mock icon component to prevent console errors. #39901, @jackw
