[ML] Job friendly Display name not shown in the UI when creating/cloning a job

[greicefaustino]

Describe the feature:
Introduced by this change, the UI uses the security_app_display_name to list the jobs names, however, when cloning a job, this field is not shown in the UI.

The request is to have also this field in the UI along with Job ID and Description so that the user can edit it during the job cloning/creation process.

Describe a specific use case for the feature:
When cloning new Jobs to another space and going to security rules and try to to select the new Job, the UI doesn't distinguish the newly created Job vs the original default Job. We see 2 ML jobs with the same name and description.

Workaround:
Edit the JSON before saving the new job to change this field.
