Describe changes:

• http: logs custom headers in a subobject

To avoid collisions, for instance for content_range

With this PR, the output will be

    "content_range": {
      "raw": "bytes 10-20/69",
      "start": 10,
      "end": 20,
      "size": 69
    },
    "response_headers": [
      {
        "name": "Content-Range",
        "value": "bytes 10-20/69"
      }
    ]

instead of

    "content_range": {
      "raw": "bytes 10-20/69",
      "start": 10,
      "end": 20,
      "size": 69
    },
   "content_range": "bytes 10-20/69"

response_headers is already used with the config option dump-all-headers
