    Called with the plain request options, right before their normalization.

    **Note:**

    **Note:**
    > - This is called every time options are merged.

    **Note:**
    > - The `options` object may not have the `url` property. To modify it, use a `beforeRequest` hook instead.

    **Note:**
    > - This hook is called when a new instance of `Options` is created.
    > - Do not confuse this with the creation of `Request` or `got(…)`.

    **Note:**
    > - When using `got(url)` or `got(url, undefined, defaults)` this hook will **not** be called.

    This is especially useful in conjunction with `got.extend()` when the input needs custom handling.

    For example, this can be used to fix typos to migrate from older versions faster.

    @example
    ```
    import got from 'got';

    const instance = got.extend({
        hooks: {
            init: [
                plain => {
                    if ('followRedirects' in plain) {
                        plain.followRedirect = plain.followRedirects;
                        delete plain.followRedirects;
                    }
                }
            ]
        }
    });

    // Normally, the following would throw:
    const response = await instance(
        'https://example.com',
        {
            followRedirects: true
        }
    );

    // There is no option named `followRedirects`, but we correct it in an `init` hook.
    ```

    Or you can create your own option and store it in a context:

    ```
    import got from 'got';

    const instance = got.extend({
        hooks: {
            init: [
                (plain, options) => {

                    }

                options => {
                    options.headers.secret = options.context.secret;

            secret: 'passphrase'
        }

    console.log(headers.Secret);
    //=> 'passphrase'
    ```

    **Note:**
    > - Got will make no further changes to the request before it is sent.

    **Note:**
    > - Changing `options.json` or `options.form` has no effect on the request. You should change `options.body` instead. If needed, update the `options.headers` accordingly.

    @example
    ```
    import got from 'got';

    const response = await got.post(
        'https://httpbin.org/anything',

Delays between retries counts with function `1000 * Math.pow(2, retry) + Math.random() * 100`, where `retry` is attempt number (starts from 1).

The `calculateDelay` property is a `function` that receives an object with `attemptCount`, `retryOptions`, `error` and `computedValue` properties for current retry count, the retry options, error and default computed value.
The function must return a delay in milliseconds (or a Promise resolving with it) (`0` return value cancels retry).

By default, it retries *only* on the specified methods, status codes, and on these network errors:
- `ETIMEDOUT`: One of the [timeout](#timeout) limits were reached.
- `ECONNRESET`: Connection was forcibly closed by a peer.
- `EADDRINUSE`: Could not bind to any free port.
- `ECONNREFUSED`: Connection was refused by the server.
- `EPIPE`: The remote side of the stream being written has been closed.
- `ENOTFOUND`: Couldn't resolve the hostname to an IP address.
- `ENETUNREACH`: No internet connection.
- `EAI_AGAIN`: DNS lookup timed out.

__Note:__ Got does not retry on `POST` by default.
__Note:__ If `maxRetryAfter` is set to `undefined`, it will use `options.timeout`.
__Note:__ If [`Retry-After`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Retry-After) header is greater than `maxRetryAfter`, it will cancel the request.

    __Note__: `prefixUrl` will be ignored if the `url` argument is a URL instance.

    __Note__: Leading slashes in `input` are disallowed when using this option to enforce consistency and avoid confusion.
    For example, when the prefix URL is `https://example.com/foo` and the input is `/bar`, there's ambiguity whether the resulting URL would become `https://example.com/foo/bar` or `https://example.com/bar`.
    The latter is used by browsers.
