feat: Refactor mech driver

After this is tested and merged, I'm aware we can do a better cleanup in workflows as we won't need undersync_device workflow anymore.
This PR needs another change in Nautobot prep_switch_interface job as from now on we can use connected_interface_uuid instead of mac_address, so please leave merging to me.

Timeouts were recently added to prevent the undersync workflow from hanging indefinitely. It might be a good idea to do that here, too.

This is implemented too

overall LGTM. Added few more suggestions for missing docstrings and type hints.

One more (optional) idea - consider updating #update_nautobot to return an instance of UUID instead of plain string, this way we add another layer of data validation which would be better than a docstring promise of returning string that happens to contain uuid.

that's a good idea, implemented
