Currently, there is a request to create a container

```gql
mutation createContainer {
  createContainer(
    image: "node:22-alpine"
    cmd: ["tail", "-f", "/dev/null"]
    labels: { test: "SDfsdf" }
  ) {
    ...DockerContainer_
  }
}

```



We get an error

```text
{
  "errors": [
    {
      "message": "(HTTP code 404) no such container - No such image: node:22-alpine ",
      "locations": [
        {
          "line": 16,
          "column": 3
        }
      ],
      "path": [
        "createContainer"
      ],
```

This is because the image has not been downloaded yet. We need to:
1\. Add a separate resolver for downloading images
2\. Add a check to the container creation resolver to see if the image already exists, and if not, download it, and only then create the container.
