Heat resources are now assigned an orchestration id prior to their instantiation by nova, cinder, et. al. This id is now added to stack lifecycle scheduler hints. In addition to nova receiving such hints, cinder is also now supported. Change-Id: I5a13feb1bdedfbbe44de15e3d9eae72e56ec8a25 Closes-Bug: #1476345
