Open Stack

Greeting folks,

I hope we can get attention from stable-maint, release-managers and
installers projects.


## Background

Some projects tried hard to follow stable policy but it didn't finish
well: https://review.openstack.org/#/c/507924/
This policy is too strict for projects like installers, although it's
not a reason why the projects wouldn't be "stable".
We decided to discuss again about the tag and how it works for installers.

## Proposal

Proposal 1: create a new policy that fits for projects like installers.
I kicked-off something here: https://review.openstack.org/#/c/511968/
(open for feedback).
Content can be read here:
http://docs-draft.openstack.org/68/511968/1/check/gate-project-team-guide-docs-ubuntu-xenial/1a5b40e//doc/build/html/stable-branches.html#support-phases
Tag created here: https://review.openstack.org/#/c/511969/ (same,
please review).

The idea is really to not touch the current stable policy and create a
new one, more "relax" that suits well for projects like installers.

Proposal 2: change the current policy and be more relax for projects
like installers.
I haven't worked on this proposal while it was something I was
considering doing first, because I realized it could bring confusion
in which projects actually follow the real stable policy and the ones
who have exceptions.
That's why I thought having a dedicated tag would help to separate them.

Proposal 3: no change anywhere, projects like installer can't claim
stability etiquette (not my best option in my opinion).

Anyway, feedback is welcome, I'm now listening. If you work on Kolla,
TripleO, OpenStack-Ansible, PuppetOpenStack (or any project who has
this need), please get involved in the review process.

Thanks,
