[libvirt] Allow multiple volume attachments
Add multiattach support to libvirt driver, by updating the
xml configuration info if the multiattach support is turned
on for a volume and set the virt driver capability
'support_multiattach' to true. This capability is set to false
for all the other drivers.
Also the attach function in nova/virt/block_device.py is updated
to call out to Cinder in case of each attachment request for
multiattach volumes, which is needed for Cinder in order to track
all attachments for a volume and be able to detach properly.
