Make UserDraftCreateCall::doit public

[kew96]

UserDraftCreateCall::doit is currently private which prevents performing the operation

[Byron]

These are private as they have public counterparts:

    /// Upload media in a resumable fashion.
    /// Even if the upload fails or is interrupted, it can be resumed for a
    /// certain amount of time as the server maintains state temporarily.
    /// 
    /// The delegate will be asked for an `upload_url()`, and if not provided, will be asked to store an upload URL
    /// that was provided by the server, using `store_upload_url(...)`. The upload will be done in chunks, the delegate
    /// may specify the `chunk_size()` and may cancel the operation before each chunk is uploaded, using
    /// `cancel_chunk_upload(...)`.
    ///
    /// * *multipart*: yes
    /// * *max size*: 36700160
    /// * *valid mime types*: 'message/*'
    pub async fn upload_resumable<RS>(self, resumeable_stream: RS, mime_type: mime::Mime) -> client::Result<(hyper::Response<hyper::body::Body>, Draft)>
                where RS: client::ReadSeek {
        self.doit(resumeable_stream, mime_type, client::UploadProtocol::Resumable).await
    }
    /// Upload media all at once.
    /// If the upload fails for whichever reason, all progress is lost.
    ///
    /// * *multipart*: yes
    /// * *max size*: 36700160
    /// * *valid mime types*: 'message/*'
    pub async fn upload<RS>(self, stream: RS, mime_type: mime::Mime) -> client::Result<(hyper::Response<hyper::body::Body>, Draft)>
                where RS: client::ReadSeek {
        self.doit(stream, mime_type, client::UploadProtocol::Simple).await
    }

Closing, as it makes no sense to edit a generated file - it will be overwritten next time the generator runs.
