The following changes have been made: (1) Create a separate node-state-transition service that is used to orchestrate changes in the node provision state (2) Extend the node list and detail UIs (actions) to support states other the manageable, available, and active (3) It should be noted that state transition actions are rendered as html list items as opposed to actions. The reason for this is that the <action> tag is not compatible with the ng-repeat directive. Change-Id: Id6543667f944c47f8f9727c1c2f3085ae75a1625
