Graded Backends

https://blueprints.launchpad.net/designate/+spec/graded-backends

Problem description

Currently we have quite a few backends, that are not tested, or actively maintained. We should be informing users of what backends are most actively maintained and tested

Proposed change

A graduated level of grading for backends:

Grade	Variations	Description
Integrated	None	Tested on every commit by the OpenStack CI Infrastructure, and maintained by designate developers as a reference backend
Master Compatible	In Tree / External	Tested on every commit by 3rd party testing, and has a person or group dedicated to maintaining compatibility on a regular basis
Release Compatible	In Tree / External	Not necessarily tested on every commit, but has a maintainer committed to ensuring compatibility for each release
Untested	In Tree / External	All other backends in the designate repository
Failing	In Tree / External	Backends that were previously "* Compatible", but tests are now failing on a regular basis.
Known Broken	In Tree / External	Backends that do not work, and have been broken with no sign of any fixes

The current backends would be currently fall into the following pattern:

Backend	Grade	Notes
PowerDNS + MySQL	Integrated
Bind	Integrated
Akamai	Release Compatible - In Tree
DynECT	Release Compatible - In Tree
Agent	Untested - In Tree
PowerDNS + pgSQL	Untested - In Tree
Microsoft DNS	Untested - External

This will also include the creation of a support matrix like Nova

This info should be maintained along with the list of current driver maintainers responsible for the "Non Integrated" backends. The upkeep of this list will fall on the PTL or his/her delegate

Should a backend's grade be in dispute, it falls on the current project PTL to make the final decision after listening to all sides concerns.
