Support `SetParameter` request on the client

[davidkleiven]

Hi,

is there currently a way of setting parameters via a SetParameter request on the client?

If there is currently no way of doing this I am happy to contribute with an implementation. I guess it would follow the same pattern as the other requests e.g. something along the lines of

func (c *Client) SetParameter(body []byte) (*base.Response, error) {
    cres := make(chan clientRes)

    req := &base.Request{
        Method: base.SetParameter,
        URL:    c.baseURL,
        Header: base.Header{
            "Content-Type": base.HeaderValue{"text/parameters"},
        },
        Body: body,
    }

    select {
    case c.chSetParameter <- setParameterReq{
        req: req,
        res: cres,
    }:
        res := <-cres
        return res.res, res.err

    case <-c.done:
        return nil, c.closeError
    }
}
