Change RPC post_live_migration_at_destination from call to cast

We don't expect post_live_migration_at_destination to return anything,
so change call to cast.

nova docker driver cannot find cgroup in /proc/mounts on RHEL

In order to support the docker hypervisor on rhel/centos or fedora
we had to adapt the function which resolves the cgroup path.

Remove unused dict BYTE_MULTIPLIERS

Dict BYTE_MULTIPLIERS in nova/common/utils.py isn't used
anywhere, and nova/openstack/common/strutils.py includes
this dict, So we can use the one in oslo if we need. It's
safe to remove it now.

Set objects indirection API in metadata service

Commit Ia12f48227eb2380f5da93313cd4045577d8857c9 introduces objects in
the metadata service.

As metadata service is supposed to be using the
conductor service for it's database access, we also need to set
nova.objects.baseNovaObject.indirection_api global to point to the
conductor API so that the object actions will be done by RPC to
conductor.

VMware: upload images to temporary directory

The patch ensures that new images are uploaded to a defined
temporary directory instead of directly to the cache directory.

The reasons for this are as follows:
1. More than one nova-compute may try and upload the same image
to the datastore at the same time
2. If there are errors then the temporary folder can be purged
3. When the image is downloaded it will be moved to the cache
directory. Only once an image has been successfully downloaded
will it be moved. This will help with false positives with
cache image deletion

The first phase of blueprint vmware-image-cache-management.

libvirt: Fix confusing use of mox.StubOutWithMock

The code was using a side effect of mox.StubOutWithMock to reset
libvirt_driver.LibvirtDriver._conn after a test before resetting it manually.
This code is shorter, and it's obvious what it does.
