1. Proposed title of this feature request

Leapp preupgrade should run on ansible provider instead of script.

2. What is the nature and description of the request?

Currently, the leapp preupgrade template runs on script provider and the leapp upgrade template runs on Ansible provider. If the environment solely uses pull-mqtt as the transport, preupgrade would complete but the upgrade would fail.

3. How would you like to achieve this? (List the functional requirements here)

For consistency, Leapp Preupgrade and Upgrade job templates should both be Ansible based jobs.
