Read the new docs: [Header Parameter Models](https://fastapi.tiangolo.com/tutorial/header-param-models/).

#### `Cookie` Parameter Models

Use Pydantic models for `Cookie` parameters:

```python

    assert response.json() == "foo"
    assert response.headers["content-type"] == "application/x-level-1"
    assert "x-level0" in response.headers
    assert "x-level1" in response.headers
    assert "x-level2" not in response.headers
    assert "x-level3" not in response.headers
    assert "x-level4" not in response.headers
    assert "x-level5" not in response.headers


def test_level1_default():

    String API_JSON_RESPONSE_HEADERS = "api.json.response.headers";

    /** The key of the configuration. e.g. false */
    String API_JSON_RESPONSE_EXCEPTION_INCLUDED = "api.json.response.exception.included";

    /** The key of the configuration. e.g.  */
    String API_GSA_RESPONSE_HEADERS = "api.gsa.response.headers";

    /** The key of the configuration. e.g. false */

  // +optional
  optional string scheme = 4;

  // Custom headers to set in the request. HTTP allows repeated headers.
  // +optional
  repeated HTTPHeader httpHeaders = 5;
}

// HTTPHeader describes a custom header to be used in HTTP probes
message HTTPHeader {
  // The header field name
  optional string name = 1;

  // The header field value
  optional string value = 2;
}

### Other (Cleanup or Flake)

- Client-go header logging (at verbosity levels >= 9) now masks `Authorization` header contents ([#95316](https://github.com/kubernetes/kubernetes/pull/95316), [@sfowl](https://github.com/sfowl)) [SIG API Machinery]
