Workflow Idea for 4.10

[Alex Fiestas]

Hi there

At Active sprint we've used a lunch break for talking about some
"Workflow Issues" we find with the current way of using git in the
workspace, just for mention a few discussed things from the top of m
head:

- People merge things not ready to be merged (aka using git as we did svn)
- We don't want to change to a 3 month release (or something like that).
- Reviewboard is not the perfect tool for big changes
- Current time schedule has its benefits

The resulting workflow if we take into account all of that is:

- Keep the 6 month release period
- Keep the current  schedule (soft freeze, hard freeze...)
- Move to a review based workflow before hard freeze (we need gerrit).
- Once we are on hard freeze, open merge for everyone so we can
continue fixing things easily.

Putting manpower aside, I think that this would be a good tentative
attempt for moving to a different thing, we keep a lot of the good
things we have right now and it will allow us to explore the benefits
of the merge based workflow.

What do you think of it?

BTW don't mention what we don't have enough reviewers, that's
something that can be work on later, ATM let's just assume we have
infinite man power ;p
