Integrate latest report generation Docker image into site

[bcspragu]

This PR updates the async task runner to support the new base image (which comes from [1]).

This includes things like:

• Uploading the new output directories (summaries + analysis)
• Fixing report paths so we can render the new reports
• Adding support for the new file types that show up in these new reports
• Supporting the new input formats (the benchmark + pacta-data dirs, input JSON, env vars, etc)

Importantly, this makes the new create-report image work locally, but doesn't do the Azure bits. That'll come in the next PR.
