[ISV-5091] Optimize container tool storage configuration

- Adds a new Ansible step controlled by the boolean variable optimize_build_storage to apply a storage configuration that saves disk space and make podman build execution safer
- Adds extra parameters variable to podman build command. This allows to easily add new configuration options and for debugging. The real fix to the issue is to setup overlay as storage driver.
