CI requirement for beman standard

Per: Beman standard,
This discussion relates to the Draft CI requirements by wusatosi · Pull Request #61 · beman-project/beman · GitHub , my suggestions to add CI requirements to the beman standard.

The exact wording is to be further refined, current draft mostly concerns about the general idea of what would be included.
