[Discover] Report kibana:plugin_render_time metric event

[jughosta]

• Closes [Discover] Report kibana:plugin_render_time metric event. #186129

Summary

This PR adds kibana:plugin_render_time EBT performance event to Discover plugin. It will be fired when user navigates to one of Discover main views:

• Discover Documents tab (when the first data grid row is rendered)
• Single Doc page (when tabs are rendered)
• Surrounding Docs page (when the first data grid row is rendered)

If the initial page was something else (like error, no data view, Field Statistics tab, etc), then it would report it too and we skip any further tracking as it would not report the correct time between the page visit and getting to the main content. Also navigation between Discover routes will not trigger the event.

Testing

Enable "Usage collection" global setting.

Navigate to Discover and observe kibana-browser requests in Network tab. It will be one of performance_metric event.

To enable logging, add the following to your kibana.dev.yml:

# Configure Analytics (EBT) Logs
logging.loggers:
  - name: analytics
    level: debug

logging.browser.loggers:
  - name: analytics
    level: debug
