Emilien Macchi c80fd4ed60 Amend reference/PTI with supported distros 
It became clear that Ubuntu and CentOS are the 2 most-popular platforms
when deploying OpenStack.

https://www.openstack.org/assets/survey/April-2016-User-Survey-Report.pdf

We recently saw some cases where some projects implemented some features
that could not work on these platforms.

Example: https://review.openstack.org/#/c/401985/
- A feature in Neutron couldn't work with latest CentOS.
- Neutron and more projects are not gating on CentOS platform, only
  Ubuntu.

The goal of this change is to document that we would like to support
Ubuntu and CentOS in our testing and also collaborate with distros when
a dependency is not fresh enough to bring new features in OpenStack.

Consistent Testing Interface

OpenStack has a lot of projects. For each project, the OpenStack CI system needs to be able to perform a lot of tasks. If each project has a slightly different way to accomplish those tasks, it makes the management of a consistent testing infrastructure very difficult to deal with. Additionally, because of the high volume of development changes and testing, the testing infrastructure has to be able to pre-cache artifacts that are normally fetched over the internet. To that end, each project should support a consistent interface for driving tests and other necessary tasks.

The following tasks are required for every project. Every project must:

  • Execute tests
  • Enforce code style
  • Generate a code coverage report
  • Generate a source tarball
  • Generate documentation

The following are other common tasks, which may not be relevant for every project:

  • Enforce code coverage
  • Generate a release artifact
  • Publish a release artifact
  • Import translation strings
  • Export translation strings

Tools and approaches vary by language, please choose which language is relevant to you.

The following operating systems are the most popular when deploying OpenStack:

  • Ubuntu (latest LTS)

  • CentOS (latest stable)

    Note

    The CentOS distribution is derived from the sources of Red Hat Enterprise Linux (RHEL). In reality, RHEL is more popular than CentOS but we can't use this platform on upstream gates, so we rely on CentOS.

Each project should run some functional tests on these platforms so we make sure OpenStack works with distros used in production. The scope of these functional tests are discussed for every project, and may adjust their coverage depending of resources and support investment. These tests are run by using existing tooling, which comes with a reasonable expectation that it's viable on the indicated distributions.

Sometimes, these distributions might not support all dependencies required by new features in OpenStack. Development of these features should not be blocked, though it has to be documented in project release notes, and some tests might have to be skipped on these distributions.
