Matt Riedemann e279ac4046 Make ResourceTracker.stats node-specific 
As of change I6827137f35c0cb4f9fc4c6f753d9a035326ed01b in
Ocata, the ResourceTracker manages multiple compute nodes
via its "compute_nodes" variable, but the "stats" variable
was still being shared across all nodes, which leads to
leaking stats across nodes in an ironic deployment where
a single nova-compute service host is managing multiple
ironic instances (nodes).

This change makes ResourceTracker.stats node-specific
which fixes the ironic leak but also allows us to remove
the stats deepcopy while iterating over instances which
should improve performance for single-node deployments with
potentially a large number of instances, i.e. vCenter.

Conflicts:
      nova/compute/manager.py

NOTE(mriedem): The conflict was due to not having change
Iae904afb6cb4fcea8bb27741d774ffbe986a5fb4 in Pike.

NOTE(mriedem): The check for node is None was moved from
_do_build_and_run_instance to build_and_run_instance because
the functional tests are using the ChanceScheduler since we
don't have change I12de2e195022593ea2a3e2894f2c3b5226930d4f
and the ChanceScheduler does not return the nodename during
select_destinations so the compute has to get it from the
driver.

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:
