Open Stack

Hi,

The following 3 changesets in the queue:

https://review.openstack.org/#/c/43274/
https://review.openstack.org/#/c/43278/
https://review.openstack.org/#/c/43280/

make keypairs, scheduler hints and console output part of the V3 core
api. This essentially changes just two things:

- the v3 API server will refuse to startup if they are not loaded (this
  is the definition of a feature being part of core given that all of
  the API is an 'extension' now.
- the resource is accessed slightly differently - /v3/keypairs rather
  than /v3/os-keypairs as an example

In terms of risk the change is limited to the V3 API only. And although
the V3 API will be experimental in Havana anyway and subject to some
change I would like to include this because of the resource name
changes and minimise any hassle for people who do start using the V3 API
in Havana and then want to use it for Icehouse. It has similar
downstream effects on documentation.

The patches are ready to go (recently its just mostly been rebase
updates with some very minor fixups).

Regards,

Chris
