Middleware wrapper logic for asynchronous functions.

```js

const wrapr = require('wrapr');

const fetch = require('node-fetch');

wrapr.retrying(wrapr.throttling(fetch))('https://example.com');

wrapr.retrying(wrapr.throttling(args => fetch(args.init, args.url)))({

  url: 'https://example.com',

  init: {

    method: 'POST',

    headers: { 'content-type': 'application/json' },

    body: JSON.stringify({ foo: 1 }),

  },

});

wrapr.retrying(wrapr.throttling(async url => {

  try {

    return await fetch(url);

  } catch (err) {

    if (err.message.startsWith('HTTP')) {

      throw new wrapr.NonRetryableError(err.message);

    } else {

      throw err;

    }

  }

}))('https://example.com');

```
