Implement support for streaming images from Glance when using the XenAPI virtualization backend, as per the bexar-xenapi-support-for-glance blueprint.
Images may be streamed raw, or will be streamed into the right place to allow room for an MBR and partition table, if using non-raw images. PV vs HVM detection now occurs on the image, immediately after it has been streamed. External kernel / ramdisk are also supported in this mode.
Unit test changes include a partial Glance simulator, which is stubbed in place of glance.client.Client. This allows us to pass through the VM spawn path with either glance or objectstore backends enabled; the unit tests now cover both. A dependency upon glance has been added to pip-requires, in order to pull the Glance client code into the venv.
This includes minor fixes to nova.image.glance. This code is expected to be heavily reworked anyway with the image-service-use-glance-clients work.
