Image/alias detection fails after first successful creation of image in deployment

[James Page]

Four node compute cluster; first nova boot works fine, however subsequent boots, which get scheduled to different hosts, fail - the driver is not creating the image and alias in LXD.

Looking at https://github.com/lxc/nova-compute-lxd/blob/master/nclxd/nova/virt/lxd/container_image.py

https://github.com/lxc/nova-compute-lxd/blob/master/nclxd/nova/virt/lxd/container_image.py#L168

On creation of an alias, the driver updates the properties lxd-image-alias and lxd-manifest in glance.

This seems odd - why would nova update image properties on a glance image?

This then causes subsequent calls to hit https://github.com/lxc/nova-compute-lxd/blob/master/nclxd/nova/virt/lxd/container_image.py#L54

which causes a silent return of the property 'lxd-image-alias' is found on the glance image, causing container creation to fail.

I suggested dropping the update of glance metadata - this seems wrong.
