Support multi-stage pipelines (multiple reports) and retries

We can use https://github.com/maciejmaciejewski/azure-pipelines-protractor for inspiration (@robertlyson thanks so much for finding this)

@robertlyson perhaps you would like to take a shot at this instead of the YAML display issue? ;)

I would love to see this functionality of publishing multiple reports.

[rouke-broersma]

Me too ;)

I am planning to do this eventually and it is high up on my priority list but my time is limited and I have to spread it across multiple open source projects.

I made a PR #387 for multiple reports
Its very simple, but i think that helps a little.

Since #387 we now support multiple reports in the same pipeline run. This issue remains open for multiple reports from multiple pipeline runs.
