Add panel to CI dashboard with metrics for build logs
Description
This merge request adds metrics for build logs to Verify / Continuous Integration dashboard.
- Invalid build logs detected. This includes mutated build logs too. Non-zero values are expected.
- Corrupted build logs detected. Anything more than zero indicates a problem.
- The per second rate of all operations happening. To make it easier to triage possible problems by looking at a single graph.
- Build logs received rate in bytes per second.
