Support building wheels (PEP-427)

Universal is used to identify pure-Python module(by bdist_wheel). For
these, it is sufficient to build a wheel with _any_ Python ABI version
and publish that to PyPI (by whatever means).

Fix the calls of webob exception classes

The webob exception classes has "explanation" arguments but some
methods calls the classes with invalid arguments. This patch fixes
them.
In addition, this patch changes the error handling of agent_build
_create() because the method raises AgentBuildExists exception only.
The API of v3 has already done it.

Fix HTTP methods for test_attach_interfaces

delete() method of attach_interfaces API is routed when specifying
"DELETE" as HTTP method, but some tests specify "POST". This bug
does not affect the test behaviors because the tests do not check
API router behaviors and just checks delete() method behaviors.

However, this patch fixes this bug because the bug confuses the
API router behaviors.

Fix the explanations of HTTPNotFound response

Nova wsgi framework gets "explanation" from HTTPNotFound exception and
outputs it into a response body as "message" attribute. Now some error
explanations are passed to HTTPNotFound exception without explanation
argument and they are not output to a response body. As the result,
the default message "The resource could not be found." of wsgi library
are output to a response body instead.

This patch fixes them to output right message to a response body.

Rescue API handle NotImplementedError

There are several nova virt drivers that don't implement the rescue API,
but the os compute API doesn't handle NotImplementedError,
it returns a 400 instead of a 501.

The patch add the proper logic to return a 501 instead.

VMware: delete vm snapshot after nova snapshot

When performing a nova snapshot, the vmware driver takes a VM snapshot
and copies out the snapshotted disk. After the operation, the VM
snapshot should be deleted, to prevent growing disk chain(s) on each nova
snapshot.

Make sure instance saves network_info when we go ACTIVE

This makes sure that when we do a save() on our instance during
creation, that we don't save the empty network_info we created
earlier over a potentially-full one built during the process.
This may happen since we wrap the networkinfo in the async helper.
This also moves the network_info.wait() out from under a conditional
which could cover up other issues leading to a case where it is
None (which shouldn't be possible). If we didn't call wait(),
then saving it wouldn't be productive or correct.

Remove bad log message in get_remote_image_service

There was a LOG.debug() message in the
nova.image.glance.get_remote_image_service() call that was incorrect and
misleading:

LOG.debug(_("fetching image %s from glance") % image_href)

This function actually does not fetch any image from Glance -- rather,
it is just used to get the default image service object or an image
service object for use with a remote Glance server.

VMware: fix rescue disk location when image is not linked clone

A rescue of a VM that has an image which is not linked clone would
create the rescue disk in the original VM's folder and not in the
rescue VM's folder. When the unrescue takes place the rescue disk
will not be deleted.

The patch adds unit tests that validates that the rescue disk location
is correct.

Increase volume creation max waiting time

In some cases waiting 60sec, is not enough for cinder volume to be created.
For example, a 20Go LVM volume (hosting a Windows Image) would take 100sec
to be copied assuming a 200Mo/s cinder volume backend.

Issue has already been discussed in I6bcd395a where a config option was
rejected.

This patches raises the max timeout at 180sec.
