AnsibleTower Provision_from_bundle no longer exist?



Does anyone know why provision_from_bundle is no longer exist in the newer version of ManageIQ/Cloudforms (Fine version)?

I understand that this path is deprecated on the new version:

and instead this path exists:
/AutomationManagement/AnsibleTower/Service/Provisioning/StateMachines/Provision/ BUT there is no provision_from_bundle there.

My objective is to create service catalog bundle where the first step is to provision a VM and the next thing is to do post provisioning steps using Ansible Tower.

Any guidance/hint on this?
