add etcd test analyzer build and integrate into measure-test-flakiness workflow

[chaochn47]

The PR is to address the ask from #13167 (comment). @serathius

The workflow stays running every Sunday midnight.

Measure-test-flakiness workflow output will additionally show the top contributor of the failed Tests name in Test/Test-arm workflow (only covers integration tests right now) in the past 1 week.

Example output https://github.com/chaochn47/etcd/actions/runs/4546435089/jobs/8015061879

Running against E2E workflows does not produce meaningful output, need to investigate more in the tool

Maybe @endocrimes can help shed lights on the issue.

E2e tests don't upload Junit reports. #13152
Definetly something worth doing now, with the new tool.
