support for non-string type request

[MohibWasay]

Plugin currently only supports requests that are for jsonapi,

updateTrainer(trainer: string): Observable<Response> {
  return this.httpClient.post('trainer', trainer);
}

Need support for non-string body based requests

updateTrainer(trainer: Trainer): Observable<Response> {
  return this.httpClient.post('trainer', trainer);
}

Can you explain the use case ?

[MohibWasay]

    post(url: string, body: string, options?: RequestOptionsArgs): Observable<Response> {
        let opts: RequestOptionsArgs = this.build(RequestMethod.Post, url, options, body);
        return this.request(url, opts);
    }

What if my body is not a string? This enforces me to transform my request object to string.
