Matt Riedemann dbce613a9a Add recreate test for RT.stats bug 1784705 
With change I6827137f35c0cb4f9fc4c6f753d9a035326ed01b in
Ocata, we changed the ComputeManager to manage a single
ResourceTracker and that single ResourceTracker will
manage multiple compute nodes. The only time a single
nova-compute service hosts multiple compute nodes is for
ironic where there is a compute node per instance. The
problem is the ResourceTracker.stats variable, unlike the
ResourceTracker.compute_nodes variable, is not node-specific
so it's possible for node stats to leak across nodes based
on how the stats are used (and copied).

This change adds a functional recreate test to show the issue
before it's fixed. The fixture setup had to be tweaked a
bit to avoid modifying class variables by reference between
test cases.

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:
