Discussion: Internal - Project & Releases management

Echoing #569, I would like if we could talk about our project management and lay out some guidelines here, in order to streamline the releases and be able to deliver new versions more quickly.

Here's my take on the subject:

#### Deprecate milestones

In order to avoid confusions, we should only be using the [GitHub project management](https://github.com/gitpoint/git-point/projects) interface to handle releases.

Milestones should be removed.

#### Project management usage

Only issues should be referenced in cards, no pull-requests.

Proposed columns:

* Proposed: Issues proposed for the release. Inclusion to be discussed.
* Todo: Issues approved & pending for this release
* In progress: Issues that were Todo and now have a WIP PR
* Ready for review: Issues that were Todo and now have a ready PR
* Completed: Issues that were Todo and are now merged in

#### Release manager

I think it would be really nice if we designate a release manager by release, to ease things up on @housseindjirdeh.

The RM responsibility would basically be:

* Discuss & move items from "Proposed" to "Todo" or other when a consensus have been reached
* Make sure the project management interface stays up to date for his release
* Revive pending PRs/Issues that needs to be addressed when they go silent for too long

#### Release QA

Either the RM, or another person should be tasked for QA during the release development.
This person would regularly test the app for regressions and post comments / new issues if needed.

@housseindjirdeh would be responsible for the last QA testing before the new version is pushed to stores.

The QA should be performed on both Android & iOS. (and we can have multiple QA members).

Here, I'm not sure if we want to change the QA team for every release, or if some people may want to take this role more permanently.

### Releases branches

This have been discussed on gitter, but I'm not sure we have decided yet how we could better use our git branches or tag to help with this. I personally lack the git-project management knowhow to propose something.

This needs to be addressed in order to be able to have real semantical releases (no more new features in patch releases)

How do **you** feel about this? What would you change?
