Allows use of Mistral workflows during deployment steps
Introduces a general mechanism meant to allow for the execution of workflows during the deployment steps. Services can define workflow actions to be triggered during a step in the newly added service_workflow_tasks section. The syntax is: service_workflow_tasks: step2: - name: my_action_name action: std.echo input: output: 'hello world' Implements: blueprint tripleo-ceph-ansible Depends-On: If02799e7457ca017cc119317dfb2db7198a3559f Depends-On: Ibc5707f9f06266fe84ad1dd91dcb984157871d30 Change-Id: I36a642fbc2076ad9e4a10ffc56d6d16f3ed6f27a
