It would be useful to be able to specify multiple Context's in a workflow. As a general best security practice, any given workflow should only have access to the secrets that it absolutely needs. In order to accomplish this with Context's currently however, many projects would need their own Context, containing only the secrets relevant to that project. This defeats the point of Contexts, making them less reusable. Allowing a workflow to specify multiple Contexts maintains this principle of least privilege, without sacrificing the usability of Contexts. Exampe:
workflows: main: jobs: - example-job: context: - AWS - Heroku - Cloudflare
