Display custom meta information per step in build

It would be interesting to define a standard for meta in which users could supply some data in the build that could be surfaced to the build page.

For Example:

meta set step.test.ui_output "Tests: 889/889 Coverage: 98%"

Results in:

I love it! We just have to take into account that meta is global for the entire pipeline, not just the job.

This would be super useful. Currently there is no easy way to see the test results and it is time consuming to dig into the logs.

Does this exist now? https://docs.screwdriver.cd/user-guide/metadata#coverage-and-test-results Although I would love to see this for other use cases as well - errors, artifact links, and other kinds of user messages.
