Placement API should support DELETE /resource-providers/{uuid}/inventories

[Jay Pipes]

This is a small feature request.

Currently (version 1.3 or before of the placement API), in order to delete all inventory for a resource provider, one must call PUT /resource_providers/{uuid}/inventories and pass in the following request payload:

{
  'generation': <int>,
  'resources': {}
}

it would be easier and more intuitive to support DELETE /resource_providers/{uuid}/inventories with no request payload and returning a 204 No Content on success.

Note that this will require a short blueprint because it touches the API and will require the following:

1) Changes to /nova/api/openstack/placement/handlers/inventory.py
2) A reno note advertising the additional placement REST API microversion and functionality

[Chris Dent (cdent)]

Just for clarity, it is also possible to delete a single inventory at a time, so the other process would be to GET /resource_providers/{uuid}/inventories, and then DELETE /resource_providers/{uuid}/inventories/{resource_class} for each class of resource that is present.

Yes, just put this on hold for a while due to Ocata freeze... this has been pushed to Pike. Also to stop the frenetic increase of microversions so don't need to update the patch all the time with daily rebases. I'll update the patch this week.
