Fixes race cond between delete and confirm resize

If we delete an instance after a confirming resize operation,
and if the instance is deleted firstly at the dest compute node,
then the *_resize dir and network info of this instance will be
left alone on the source compute node, never be cleaned up.
Please refer the bug page to get the reproduce steps

Catch more accuracy exception for _lookup_by_name

When an instance is not found by libvirtd, _lookup_by_name in libvirt
driver raises InstanceNotFound. This patch catchs this exception instead
of NotFound who is the father of InstanceNotFound.

xenapi: ensure pool based migrate is live

The current code is missing a flag to pool_migrate that should be
included to ensure the migrate is live. This change adds that flag to
both uses of VM.pool_migrate, namely the live-migrate call and the
host_maintenance call.

xenapi: add tests for finish_migration and spawn

Before making finish_migration and spawn share more code, lock down the
current code with unit tests.

There are also some methods that are split up, to help with some of the
next refactoring steps.

xenapi: stop injecting the hostname during resize

The windows PV tools will set the hostname of a server to the value
given in the hostname xenstore key. If we inject that during resize, the
users will be unable to change their server hostname, and in addition it
will be reset to the original name.

xenapi: regroup spawn steps for better progress

Currently the operations are not very logically grouped. Now we can see
all the individual actions more clearly, we can re-arrange the
operations so each step make more sense, and should be better at
reporting progress.

Rather than checking very late that there is no duplicate VM and enough
memory, I have moved these checks before the expensive operation of
downloading the disk.

After this change there are 10 clear steps during spawn:
* initial step so progress is not zero during download disks
* download and create disks step
* download and create kernel and ramdisk step
* create the VM record, now the disks have been downloaded
* setup the disks; resizingi up disk, and attaching, adding rescue disk
* injecting instance data, currently this means writing to xenstore
* setting up the networking, including the initial firewall setup
* starting the VM and waiting for it to boot
* configuring the VM using the agent (takes a long time on windows)
* applying the final firewall filters, now the VM is running

With this in place, it will be easy to decide which steps are required
and which are not required when reusing the spawn code to implement
finish_migration in a later change.

Improve "keypair data is invalid" error message

When doing a keypair-add, I was hitting a permission denied issue with
ssh-keygen -l. This turned out to be a configuration issue, but the
error message on the client side was pretty unhelpful with debugging
the issue:

  BadRequest: Keypair data is invalid (HTTP 400)

Fix that so we get:

  BadRequest: Keypair data is invalid: failed to generate fingerprint (HTTP 400)

Also fix the other uses of InvalidKeypair so we include the general
"keypair data is invalid" prefix.

Fix network info injection in pure IPv6 environment

get_non_legacy_network_template assumes that IPv4 is always available

So if i try to use Nova Network without any ipv4 using say
"nova network-create public --fixed-range-v6 fd8c:215d:178e:452:0:0:0:0/64"
then the deployment fails. So fix the code to ensure ipv4 is optional

Fix snapshot failure with VMwareVCDriver

The snapshot operation was failing because it calls
VirtualDiskManager.CopyVirtualDisk with a destination disk spec, which
is not supported when called through VC. The fix is to not supply a spec
when calling through VC, in which case the disk is consolidated and
copied without type transformation.

While the fix is to use spec-less CopyVirtualDisk in VC, doing so in ESX
too will result in unintended transformation (because it ESX will
default to busLogic/preallocated), so the use of the spec was retained
in ESX-mode instead.

Another issue found and fixed is that the name of the snapshot image is
incorrectly set when uploading to glance.

The following tempest tests are now unbroken against the VC and ESX
nodes:
  tempest.api.compute.images.
     test_images_oneserver.ImagesOneServerTest{JSON,XML}.
        test_create_delete_image
        test_create_second_image_when_first_image_is_being_saved
        test_delete_image_of_another_tenant

Fix problem with starting Windows 7 instances using VMware Driver

The default controller for a Windows 7 virtual machine is the
LSI Logic SAS. When the disk adapter type is specified as 'lsiLogic'
via glance image metadata, VMware driver defaults to LSI Logic Parallel
controller. With this fix the driver will honor a property 'lsiLogicsas'
to distinguish the right adapter and enable booting Windows instances.
