This removes the DB calls from the extension and moves them into
HostAPI(). The cells version of HostAPI() proxies them to the
appropriate cell or cells.

Adds task_log_get_all() call to HostAPI() so that we can use the local
DB when cells is disabled or proxy via cells if cells is enabled.

This moves the last bit of compute-initiated db accesses found during
test runs to conductor. The quantum API was hitting the database directly
while calling back to compute's API to trigger the refresh. This just
makes the quantum API ask conductor to do that in a similar way to the
usage notifications patch recently merged.

Fixes bug 1101587.
* nova/locale/en_US/LC_MESSAGES/nova.po: This "translation" was
woefully outdated, causing KeyError exceptions under a number of
circumstances for users of this particular locale when format
strings wound up containing incorrect substitution variables. This
change attempts to sync up the msgstr entries to match msgid given
this is the source language for the pot file. I did not see any
obvious instances where en_US should differ from C locale for these.

5f697f64e5c445ba1b62c82d9167fd6b9c7256d2 introduced a regression
when using lxc containers with qcow2 and qemu-nbd.
When removing the rootfs from the host namespace, it would
terminate the qemu-nbd process as well. This would cause
the kernel too oops under Ubuntu 13.04. Since the underlying
device thtat the libvirt_lxc process disapears.
To get around this we just clean up the host namespace if the
instance is powered-on. When the instance terminates it will
teardown the whole container.
This fixes LP: #1115786

This is mostly a refactoring so that if config drive is required,
variable lookup only needed for the injection case, is avoided.
There is a functional change here to make 'admin_pass' consistent
with the other variables in that the libvirt_inject_password flag
now does _not_ control whether the admin password is placed
in the config drive.

The Hyper-V driver contributed for Folsom contains some refactored code
from the Diablo release contributed by Cloud.com.
Although the copyright notice remained in the "driver.py" file, it has
erroneously not been added to the new "vmops.py" and "vmutils.py" files
that contained some refactored code from the original contribution.

This will allow the hosts API extension to work. Calls to get service
information from the DB are proxied via cells.
When using the host extension, the 'id' and 'host' fields for
service/compute will be modified to have the cell prepended to it. One
can do a 'show' on a 'path!to!cell@id' to see details for a particular
host in the 'path!to!cell' cell, for instance.

This allows for an image in glance to be annotated with a
property describing the required disk / cdrom bus type.
eg
# glance image-update \
--property disk_bus=ide \
--property cdrom_bus=ide \
f16-x86_64-openstack-sda
Valid bus values vary per the libvirt_type setting:
qemu/kvm: 'virtio', 'scsi', 'ide', 'usb'
xen: 'xen', 'ide'
uml: 'uml'
Requesting an unsupported disk bus will cause the guest
instance to fail to launch.

Currently the libvirt disk bus is fixed at the time the driver
is started. The get_guest_storage_config and _create_image
methods thus use some variables initialized in the libvirt
driver constructor to determine disk bus / dev name mappings.
It will shortly become possible to configure a different disk
bus per instance, which invalidates the current assumptions
in the code. A further complication is that the _create_image
and get_guest_storage_config methods needs to duplicate each
others logic for determining disk mapping.
To simplify the current code and make it more make flexible
introduce a new 'blockinfo.py' module in libvirt, and with
it a 'get_disk_mapping' method & associated helper APIs. This
method is responsible for examining the instance type and
block device info dicts and figuring out the complete list of
disks that will be attached to the guest & their optimal
disk bus + dev name values. This info is returned in a dict
and then passed to _create_image and get_guest_storage_config
Thus the logic for determining disk dev names is now isolated
in one single place, separate from the main driver code, so
it has no need to rely on state in the driver object.
Many, many test cases are added to try to thoroughly validate
the disk mapping code, since there are a huge set of possible
configurations the user may request, making it easy to break
the code accidentally.

This patch makes compute manager call notify_usage_exists() via the
conductor instead of directly, avoiding the direct database access
required to fetch bandwidth information. I initially just added
a notify_bw_usage() method to conductor, which just handled the
bandwidth part (which is the database hit). However, the metadata
payload part may be depended upon by custom stuff for periodic
notifications, so copying all that stuff as well made it a bunch
of duplicated stuff. Thus, I decided to just make it a direct proxy
for the compute_utils method.
Note that this is a bit of a departure from the previous pattern of
just proxying db interfaces in conductor, but I think the simplicity
gain is worth it.

The libvirt volume code is in a separate module from the
main libvirt driver code, so it makes sense for the test
suite to be separated too, to make it easy to quickly
run just the volume tests. This has the added advantage
of reducing the size of the enourmous test_libvirt.py
file which is becoming unwieldly.

For inexplicable reasons the NFS volume driver was put into a
different file than all the other libvirt volume driver impls.
The NFS code isn't so large & complex that it needs to be in
a different place than everything else. Move the code into
the main volume.py file.
To avoid breaking existing deployments, the original class
has to be a trivial subclass of the new module. Any use of it
will trigger a deprecation warning. This allows time for users
to update their 'libvirt_volume_drivers' config (in the unlikely
event they have altered from the default setting).

Added test case and support functions for CI opportunistic testing
using a PostgreSQL database, as part of our postgresql as a first
class citizen effort.
rebased again on top of test migration with data framework
clean up debug, and ensure pg will fail to connect gracefully
fix previous migration test which was inserting a key by id, which
postgresql doesn't like, as it doesn't adjust the autoincrement
counter.
added driver to connection string for mysql
Updated comment to expose how to do this on pg easily

This refactors the set_password() method in the server_password
API extension to merely format the metadata and return it, leaving
the job of updating the database to the caller. In the API extension
case, the update can be done immediately against the database as
before. In the case of the metadata API handler and the xenapi virt
driver making the call, conductor can be used to update the instance's
system_metadata, thereby avoiding a direct database access.
