Updates the libvirt volume driver so that it properly handles
exit code 21 in the active session check. This fixes issues
in running the command on Fedora 17.
This behaviour was broken in 933365a (multipath libvirt iscsi).
Fixes LP Bug #1130718.

This enhances IPAddresses tests to check if the migration goes fine with longer
IPv6, and with ipv6 that can be shortened (postgresql uses shortened form,
mysql and sqlite doesn't).
Also enhances cidr tests to check migration of shortenables cidrs, and cidrs
that postgresql suppress its prefix, like 10.0.0.0/32 cause it is pretty much
the same as 10.0.0.0

This patch contains a number of cleanups of the nova devref,
mostly related to outdated content.
1) remove outdated todo items from network
=> these have been long covered in the manuals
2) remove outdated multinic docs and images
=> this is now better covered in:
http://docs.openstack.org/trunk/openstack-compute/admin/content
/using-multi-nics.html
3) remove outdated cloudpipe docs, confs and scripts
=> This is now better covered in:
http://docs.openstack.org/trunk/openstack-compute/admin/content/
cloudpipe-per-project-vpns.html
4) remove outdated networking docs
=> These were marked as 'legacy' more than 2 years ago

The cfg API is now available via the oslo-config library, so switch to
it and remove the copied-and-pasted version.
Add the 2013.1b4 tarball to tools/pip-requires - this will be changed
to 'oslo-config>=2013.1' when oslo-config is published to pypi. This
will happen in time for grizzly final.
Add dependency_links to setup.py so that oslo-config can be installed
from the tarball URL specified in pip-requires.
Remove the 'deps = pep8==1.3.3' from tox.ini as it means all the other
deps get installed with easy_install which can't install oslo-config
from the URL.
Make tools/hacking.py include oslo in IMPORT_EXCEPTIONS like it already
does for paste. It turns out imp.find_module() doesn't correct handle
namespace packages.
Retain dummy cfg.py file until keystoneclient middleware has been
updated (I18c450174277c8e2d15ed93879da6cd92074c27a).

A new scheduler filter that allows the creation of instances from
specific tenants in selected aggregates.
With this filter is possible to isolate tenants in a specific set
of compute nodes (aggregates).
If a host is in an aggregate that has the metadata key
"filter_tenant_id" it can only create instances from that tenant(s).
A host can be in different aggregates.
If a host doesn't belong to an aggregate with the metadata key
"filter_tenant_id" it can create instances from all tenants.

Update the compute manager to register an event handler
with the compute drivers. The initial handler will process
lifecycle event notifications, to allow prompt synchronization
of DB & hypervisor power states. This means that if a guest
admin does 'shutdown -h now' the libvirt driver in Nova will
immediately notice that and mark the guest as SHUTOFF rather
then leaving it RUNNING until the periodic task runs sometime
in the next 10 minutes

This wires up the libvirt compute driver to process async
events from libvirtd and emit lifecycle events. This makes
use of the native libvirt event loop to handle I/O processing
which requires a native thread.
The native thread uses a queue + self-pipe to forward events
onto a green thread. The green thread reads events off the
queue and uses the emit_event method to dispatch them to the
compute manager.

This introduces the basic infrastructure to allow compute
drivers to emit asychronous events for processing by the
virt API. Initially the only event defined is a "lifecycle"
event which allows the virt API to immediately detect the
start and stop of virtual domain instances, without needing
to frequently poll the compute API.
The base compute driver gains a method enabling the manage
to register a callback to receive events, and another method
to allow driver subclasses to emit events.

Use fallocate where available to allocate file system blocks efficiently
when the VM is initially provisioned. This will give immediate feedback
if enough space isn't available. Also it may significantly improve
performance on writes to new blocks, and may even improve I/O
performance to prewritten blocks due to reduced fragmentation.
Also noted is the potential to subsume the less general
libvirt_sparse_logical_volumes option into the new more general
preallocate_images option.

Part 4 for blueprint quota-instance-resource, by setting cpu_shares,
cpu_quota,cpu_period through nova flavor-set with admin credentials,
the cloud admin can implement flexable policy on VM vcpu to physical
CPU consumption ratio.
for example:
nova flavor-key m1.low_cpu set cpu_quota=10000
nova flavor-key m1.low_cpu set cpu_period=20000
the instance of m1.low_cpu can only has a max of 50% CPU consumption
of a physical CPU computing capability.

Today the heartbeat information of Nova services/nodes
is maintained in the DB, while each service updates the
corresponding record in the Service table periodically
(by default -- every 10 seconds), specifying the timestamp
of the last update. This mechanism is highly inefficient
and does not scale. E.g., maintaining the heartbeat
information for 1,000 nodes/services would require 100 DB
updates per second (just for the heartbeat).
This patch adds nova.servicegroup.drivers.memcached, a
service heartbeat driver using Memcached. You can reduce
DB updates with it.
