Creating snapshot fails when image metadata has version field

Bug description:
Description:
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.
OpenStack version : Pike
Nova API version : 2.1
Steps to reporduce:
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
image used:
