feat(convert_compiler_to_legacy): gather certificate extension information

- Added steps to apply `peadm::setup::node_manager_yaml` class on the primary target.
- Ensured `primary_host` is set correctly based on the primary target's certname.
- Improved the setup process by gathering certificate extension information.

This enhancement ensures that the correct certificate data is used, improving the accuracy of the conversion process.
