This change adds a DELETE call on the server-migrations object to cancel a running live migration of a specific instance. TO perform the cancellation the virtualization driver needs to support it, in case that the feature is not supported we return an error. We allow a cancellation of a migration only if the migration is running at the moment of the request and if the migration type is equal to 'live-migration'. In this change we implement this feature for the libvirt driver. When the cancellation of a live migration succeeded we rollback the live migration and we set the state of the Migration object equals to 'cancelled'. The implementation of this change is based on the work done by the implementation of the feature called 'force live migration': https://review.openstack.org/245921 DocImpact ApiImpact Implements blueprint: abort-live-migration Change-Id: I1ff861e54997a069894b542bd764ac3ef1b3dbb2
