Matt Riedemann cd50dcaf3e Delete allocations from API if nova-compute is down 
When performing a "local delete" of an instance, we
need to delete the allocations that the instance has
against any resource providers in Placement.

It should be noted that without this change, restarting
the nova-compute service will delete the allocations
for its compute node (assuming the compute node UUID
is the same as before the instance was deleted). That
is shown in the existing functional test modified here.

The more important reason for this change is that in
order to fix bug 1756179, we need to make sure the
resource provider allocations for a given compute node
are gone by the time the compute service is deleted.

This adds a new functional test and a release note for
the new behavior and need to configure nova-api for
talking to placement, which is idempotent if
not configured thanks to the @safe_connect decorator
used in SchedulerReportClient.

Closes-Bug: #1679750
Related-Bug: #1756179

Conflicts:
      nova/compute/api.py

NOTE(mriedem): The compute/api conflict is due to not
having change I393118861d1f921cc2d71011ddedaf43a2e8dbdf
in Pike. In addition to this, the call to
delete_allocation_for_instance() does not include the
context parameter which was introduced in change
If38e4a6d49910f0aa5016e1bcb61aac2be416fa7 which is
also not in Pike.

OpenStack Nova

OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of compute technologies, including: libvirt (KVM, Xen, LXC and more), Hyper-V, VMware, XenServer, OpenStack Ironic and PowerVM.

Use the following resources to learn more.

API

To learn how to use Nova's API, consult the documentation available online at:

For more information on OpenStack APIs, SDKs and CLIs in general, refer to:

Operators

To learn how to deploy and configure OpenStack Nova, consult the documentation available online at:

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.

Further developer focused documentation is available at:

Other Information

During each Summit and Project Team Gathering, we agree on what the whole community wants to focus on for the upcoming release. The plans for nova can be found at:
