Thx @zvonkok
Just one comment left to discuss introducing Cache::new(auto_refresh:bool) {}

@Apokleos Also fixed a bug with edits, what we missed is that we might only have dev.edits and if spec.edits is None it will skip adding the dev.edits here is an example

{
            "cdiVersion": "0.6.0",
            "kind": "kata.com/gpu",
            "devices": [
                {
                "name": "0",
                "annotations": {
                    "whatever": "false",
                    "whenever": "true"
                },
                "containerEdits": {
                    "deviceNodes": [
                    {
                        "path": "/dev/zero"
                    }
                    ]
                }
                }
            ]
        }
