Split policy for board minutes into board procedures and information for the foundation at large
CC @ptomato
This is mainly about @aday's point in https://discourse.gnome.org/t/guidelines-on-meeting-minutes-approval-and-confidentiality/236 about splitting the proposed guidelines for meeting minutes into 1. Procedures for the Board and 2. Information for the Foundation at large. I'll post a split version here, or in the discourse topic; this issue is just to keep track of things.
