[Accountability-tf] RIPE Accountability Areas

Dear task force members, Attached is our initial attempt to map out some of the accountability areas. We looked at the entities that the RIPE community is structured around and tried to identify the various roles they perform. Where there is documentation supporting a particular role, we have included a link to the relevant document or web page. Towards the bottom we have also included some other relevant areas and some comments. Cheers Antony
