Description of problem:
When creating a VM from a template with custom cloud-init script, the gui does not show the userData stored in the templates yaml for the cloudinitdisk.
As a result, the VM is created without a known password and the cloud-init scripts are not run.


Version-Release number of selected component (if applicable):
2.5.3

How reproducible:
Everytime


Steps to Reproduce:
1.Create a template from a boot source image (rhel8)
2.Add some custom cloud-init configuration to the template. i used the following:
#cloud-config
user: cloud-user
password: changeme
chpasswd:
  expire: false
rh_subscription:
  org: an_org_name_or_number
  activation-key: an_activation_key
  auto-attach: true

3. Save the template
4. View the yaml for the template and the script is present.
          volumes:
            - name: cloudinitdisk
              cloudInitNoCloud:
                userData: |+
                  #cloud-config
                  user: cloud-user
                  password: changeme
                  chpasswd:
                    expire: false
                  rh_subscription:
                    org: an_org_name_or_number
                    activation-key: an_activation_key
                    auto-attach: true

5. Create a VM from the template.
6. The cloud-init page has a blank custom script.
7. Finish creating the VM with the blank cloud-init script.

Actual results:
The cloud-init script stored in yaml file is not executed. If I create another VM and paste the same script into the gui, it works as expected.


Expected results:
The Custom Cloud-init script stored in the template should automatically populate the gui and be executed once the VM is created.
