GraphQL support for queries (Improvement)

[Danushka96]

Since there are many fields for a country it will be great if GraphQL support is added. So users can request the fields they want instead of receiving unwanted fields.
Documentation will be simplified because users can tell what they want. No need of having multiple endpoints for different queries.

Hi Danush, yes this is the ultimate update we would like to make while keeping backward compatibility for the REST layer. Do you have more suggestions regarding kickstarting this? Meanwhile I'll pin this issue
