more fields in JSON output

[dshelikhov]

we are migrating from deprecated freegeoip, but echoip is missing information that we used. The change adds more fields to JSON output: zip_code, time_zone, region_name, region_code, metro_code(US only)

echoip output

{
  "ip": "37.193.173.92",
  "ip_decimal": 633449820,
  "country": "Russia",
  "country_eu": false,
  "country_iso": "RU",
  "city": "Novosibirsk",
  "latitude": 55.041,
  "longitude": 82.9428,
  "user_agent": {
    "product": "curl",
    "version": "7.47.0",
    "raw_value": "curl/7.47.0"
  }
}

freegeoip output

{
  "ip": "37.193.173.92",
  "country_code": "RU",
  "country_name": "Russia",
  "region_code": "NVS",
  "region_name": "Novosibirsk Oblast",
  "city": "Novosibirsk",
  "zip_code": "630032",
  "time_zone": "Asia/Novosibirsk",
  "latitude": 55.041,
  "longitude": 82.9428,
  "metro_code": 0
}

The output with new fields looks as follow:

{
  "ip": "37.193.173.92",
  "ip_decimal": 633449820,
  "region_name": "Novosibirsk Oblast",
  "region_code": "NVS",
  "country": "Russia",
  "country_eu": false,
  "country_iso": "RU",
  "city": "Novosibirsk",
  "latitude": 55.041,
  "longitude": 82.9428,
  "user_agent": {
    "product": "curl",
    "version": "7.64.1",
    "raw_value": "curl/7.64.1"
  },
  "zip_code": "630091",
  "time_zone": "Asia/Novosibirsk"
}

Please expand the TestJSONHandlers test to include a response with all these new fields. You can do this by setting the fields in the structs returned by the testDb functions.
