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 Co-Authored-By: Stephane Miller <stephane@alum.mit.edu> Co-Authored-By: Hironori Shiina <shiina.hironori@jp.fujitsu.com> Depends-On: I328a698f2109841e1e122e17fea4b345c4179161 Change-Id: I2347d0893abc2b1ccdea1ad6e794217b168a54c5 Partial-Bug: 1526231
