Screenshot button dialog VM provision service type

Description of problem:
The rendering of a service dialog on a custom button on a service seems to be different depending on the catalog item type. In some cases this results in no Submit/Cancel buttons, just Save/Reset/Cancel. In other cases this results in both Submit/Cancel and Save/Reset/Cancel buttons in different places

Version-Release number of selected component (if applicable):
5.9.1.2

How reproducible:
Every time

Steps to Reproduce:
1. Create a simple service dialog containing one or more text boxes.
2. Create a custom button on a service object type, that uses the new service dialog.
3. Create a service catalog item of type Ansible Playbook, and order the service
4. Create a service catalog item of type RHV/VMware (to create a VM) and order the service.
5. On each of the resulting new services, order the (same) new custom button

Actual results:
When the button is pressed on the Ansible playbook service, no Submit/Cancel buttons appear on the service dialog (see screenshot screenhot_button_dialog_ansible_playbook_service.png).

When the button is pressed on the RHV VM service, both Submit/Cancel and Save/Reset/Cancel buttons appear (see screenshot screenhot_button_dialog_vm_provision_service.png).


Expected results:
The button dialog should behave the same for all service types. Just the Submit/Cancel buttons should appear on the button dialog

Additional info:
The dialog on the Ansible playbook service seems to be rendered by the old dialog renderer, whereas the dialog on the VM service seems to be rendered by the new CFME 5.9 dialog renderer.
