Revamp promoters committee members permissions

Is your feature request related to a problem? A clear and concise description of what the problem is.

Author = the user that created the initiative in the first place

Member = user that was accepted as a member in the promoter committee

Currently members have the same permissions as the author of the initiative. A member can send the initiative to technical validation (without a way to cancel) remove and accept other members. This creates a high level of uncertaintety around the process of drafting an initiatives. We added versioning so we can at least track changes made by everyone.

Here is an exhaustive permission table for members and authors : https://user-images.githubusercontent.com/11473995/101887291-f073f400-3b9c-11eb-8c74-e01925d55bf2.png

Describe the solution you'd like

We think that distinguishing the permissions of the initial author and the co-author would help solve this issue.

Here's the updated permission table that we propose implementing :
