[FR] Openweathermap plugin for Telegraf - addition of 'wind_gust' metric

[jedd]

Use Case

Greetings,

Openweathermap plugin currently pulls two wind metrics - wind_speed and wind_direction, but the upstream API also offers the wind_gust value.

Sample output from curling the openweather api:

 "wind": {  
   "speed": 6.43,  
   "deg": 155,  
   "gust": 16.41  
 },  

Adding this to the telegraf openweathermap plugin looks to require small additions in three places in https://github.com/influxdata/telegraf/blob/master/plugins/inputs/openweathermap/openweathermap.go - a single line entry after each of the three existing

		"wind_degrees": e.Wind.Deg,
		"wind_speed":   e.Wind.Speed,

definitions, with wind_gust as the API returned key name, and e.Wind.Gust as the new internal variable.

And one line addition to: https://github.com/influxdata/telegraf/blob/master/plugins/inputs/openweathermap/types.go - adding a new entry after:

	Wind struct {
		Deg   float64 `json:"deg"`
		Speed float64 `json:"speed"`

I'd assume same type (float64 and speed) as 'Wind.Speed'.

I'd guess some adds to the output samples and the /testcases/ directory, but I'm not a go lang guy, so I'm going to avoid guessing about those requirements.

thanks,
Jedd.
