Add support for "-G" curl option

In Stripe APIs the filtering can be done by sending parameters with “-G” curl option, as example https://stripe.com/docs/api/accounts/list#list_accounts-created

curl https://api.stripe.com/v1/accounts?limit=3 \
   -u sk_test_BQokikJOvBiI2HlWgH4olfQ2: \
   -d created[lte]=1517443200 \
   -G 

When used, this option will make all data specified with -d, --data, --data-binary or --data-urlencode to be used in an HTTP GET request instead of the POST request that otherwise would be used. The data will be appended to the URL with a ‘?’ separator. From https://curl.haxx.se/docs/manpage.html

I don’t really understand how this is useful over @Query-annotated parameters. Can you please provide an example of what you are trying to achieve that is impossible with @Query and @QueryMap?

Has been almost a year now, but for someone looking for the same than @raderio, maybe this will help. With the Jake’s comment, I just looked for annotation @Query, and as an example:

@GET("Route") Observable<RoutesResponse> getRoutes(@Query("where") String query, @HeaderMap Map<String, String> headers);

I had a POJO for that query but It doesn’t work with @Query as it gives me a 500 Internal Server Error, and I just, convert it to a String with gson:

restClient.getRoutes(getGson().toJson(request), headers); // getGson() is in the RequestModel
