snapshot metadata mapper is not exist in v2 APIRouter

[Saurabh]

cinder/api/v2/router.py doesn't have mapper for snapshot metadata, but cinder/api/v2/snapshot_metadata.py exist with all actions.

So either we add mapper or delete snapshot_metadata.py.

Snapshot metadata API was implemented in in blueprint- https://blueprints.launchpad.net/cinder/+spec/update-snap-metadata . But looks like mapping in V2 router class was missed somehow.
