backend_setup role fails with ansible-core 2.13.3 and Python 3.9 about gluster-ansible-infra HOT 3 OPEN

It seems like a regression with Ansible v2.12 was helping us hide this issue till it was fixed with v2.13. Quoting some points from various related issues from Ansible:

• to_json and to_nice_json ALWAYS are supposed to return a string (of serialized JSON) otherwise they would be a Python dictionary/list. Ansible tends to automatically convert JSON into Python data structures, though we have some safeguards against it when explicitly using those filters (which would create the behavior you see).
• You should really only use to_json/to_nice_json on things that are Ansible variables

Therefore we must refrain from using to_json filter on variables within Jinja2 template.

This makes it so oVirt 4.5.4 with ovirt-node-ng-installer-latest-el8.iso (currently links to 4.5.4-2022120615) won't install.
