Add query by country in /v2/country

[Turreted]

This adds a new endpoint to /v2/ where users can query for information by country. Example: /v2/country?country=Ireland returns {"country":"Ireland","country_code":"IE","latest":{"confirmed":683,"deaths":3,"recovered":5}}

You need to pull the latest changes. The JHU (location) service is now attached to the request (see the latest route for example).

Secondly, “country” is not RESTful, you should use /countries/:country_code or name
