Add a branch label to workflow metrics

[kjkuan]

Hi,

Would it make sense to add a branch label to the workflow metrics (workflow_*)?

Our github action workflow works for both PR branches and special environment branches like, master, staging, and prod. Having a branch label in the workflow metrics would help us distinguish different types of workflow metrics when computing statistics about github action workflows.

Thanks

makes sense, are you willing to add a PR for that?

cool, my colleague has started working on it. We'll send a PR once it's ready, thanks!
