This adds support for volume_target, which is required to boot instances
from volumes.
This will expose new Python API to operate volume targets:
- client.volume_target.create
- client.volume_target.list
- client.volume_target.get
- client.volume_target.update
- client.volume_target.delete
- client.node.list_volume_targets
