Allow passing custom parameters in request body instead of as query params

I have not found a way to do this either, but it would be much appreciated.

You can find examples here:
https://docs.drone.io/api/builds/build_create/

When using the API to interact with the Drone server, I wish I could create a build with custom parameters set inside the body of the request instead in of the query params.

Instead of passing query parameters in the url, you maybe be able to pass the query parameters in the http body as form-data. If not, we would accept a pull request to do so.
