Only create volume with an active image

1. Currently cinder doesn't check whether the image is active
when create volume with an image id, we can even create volume
with a deleted/saving/queued image.

2. For deleted image, it only happened when using admin credentials.

When using non-admin credentials, it returned an error that image
is not found by using 'glance image-show' on a deleted image, which
is expected. Also when creating a volume from this deleted image,
it returned  a 404 error upfront. This again is the expected result.

When using admin credentials, we can view the details of deleted image
with 'glance image-show'. If create a volume out of an image ID (which
is now deleted), the operation succeeds, but the volume is left in
'error' state.

3. This accounts for a bug(he volume shouldn't be created) and should be fixed.
