[coc-tf] Draft Requirements Document

Dear TF members, As discussed on our last call, here is the draft requirements document Athina and I have been working on: https://docs.google.com/document/d/17ILmg_c-r_r5-0T0t7Q5a1qO8UzI4xKOUD7D73YL... Still not quite finished on our end, but I think it's best if we do this in parallel. Cheers Ant
