Matt Riedemann 74e76b1a6b Add cross-cell resize tests for _poll_unconfirmed_resizes
This adds two tests and updates the cross-cell resize docs to
show that _poll_unconfirmed_resizes can work if the cells are
able to "up-call" to the API DB to confirm the resize. Since
lots of deployments still enable up-calls we don't explicitly
block _poll_unconfirmed_resizes from processing cross-cell
migrations. The other test shows that _poll_unconfirmed_resizes
fails if up-calls are disabled.

Part of blueprint cross-cell-resize

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:

- `Compute API Guide <https://docs.openstack.org/api-guide/compute/>`__
- `Compute API Reference <https://docs.openstack.org/api-ref/compute/>`__

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

- `OpenStack for App Developers <https://www.openstack.org/appdev/>`__
- `Development resources for OpenStack clouds
  <https://developer.openstack.org/>`__

Operators
---------

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

- `OpenStack Nova <https://docs.openstack.org/nova/>`__

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:

- `Bug Tracker <https://bugs.launchpad.net/nova>`__

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:

- `Official Nova Documentation <https://docs.openstack.org/nova/>`__
- `Official Client Documentation
  <https://docs.openstack.org/python-novaclient/>`__

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:

- `Nova Specs <http://specs.openstack.org/openstack/nova-specs/>`__
