Description of problem:

When creating a snapshot of a server using the nova API, failure occurs if the image contains the metadata property "version".
It seems like image metadata is passed as an argument to _create_v2 (nova/image/glance.py) which is then passed to call (nova/image/glance.py) as kwargs. The function already takes in context, method, and version arguments, so it seems that any of these metadata properties would cause the snapshot to fail.

How reproducible:
Always


Steps to Reproduce:
1. Create an image with metadata property "version"
2. Launch an server using this image
3. Try to create a server snapshot of the server you just launched

Actual results:
Error

Expected results:
Snapshot created
