Actions: Publish custom summary documents (Server)

[github-product-roadmap]

Summary

In addition to the text log actions will now be able to publish a markdown document that will be displayed on the run summary page.

Intended Outcome

Actions like test runners, and linters often want to provide a richer experience for their output than is possible with simple text.

How will it work?

An action author will have a new method in the toolkit that will let them write markdown formatted content to a summary file that is automatically created per action in a job. On completion of each action the summary file is automatically uploaded and will be displayed on as part of the run summary.
