This spec proposes a new Heat resource type -  OS::Mistral::WorkflowExecution .
This new resource type will enable more control on execution of Mistral 
workflows when deploying a service in heat.
Specifically it will  provide feedback whether the execution succeeded or 
failed, which is important in cases where the workflow execution is an 
important part of the stack (preparation, post configuration, etc.) and if that 
fails we would like to fail the stack creation.
Moreover it will it will simplify stacks of use cases in which there is a need 
as part of the deployment to create resources and  run the workflows in a 
certain order

Please review the spec [1]<http://review.openstack.org/267770> -
