Asserts: Multilane insights and annotations

[bohandley]

This is in progress for Logs, but can be added for other Drilldown Apps.

See this doc for plans.

From doc:

The Asserts insights timeline widget component extension was released as a PoC for ObsCon to show the capabilities of integrating Asserts into more contexts throughout Grafana (e.g. Drilldown).
However, as the component is not currently part of the visualization, there are a few classes of problems that arise:

• UI
  • It is not obvious that it is aligned with the x-axis of the time-series panel
  • Inconsistent with other visualizations
  • Rendered below the legend
• Data
  • Component makes 3 API calls
  • Each instance of the component makes duplicate API calls
• Integration
  • Component only takes service_name label
  • The component was not designed to be integrated in multiple panels
  • Must be manually added below individual visualizations
  • React component cannot be integrated with visualizations in scenes
    • Preventing use in drilldown panel grids and other application/dashboard contexts

We are really close! I believe the following two PRs are the correct POCs for implementing multilane annotations:

#1140
https://github.com/grafana/asserts-app-plugin/pull/2952

The above PRs make a separate data layer call for each KG severity level. This returns a frame for each severity which is mapped to a different lane with a different color.

The PRs below show that the current implementation flattens the severity lanes into a single red annotation lane. We are cloase but the following PRs are not yet multilane. I believe the above POCs will get us the true multilane solution.

Current Metrics drilldown PR with single red lane
