  /**
   * Clients accept an array of constructor parameters.
   *
   * Here's an example of creating a client using a base_uri and an array of
   * default request options to apply to each request:
   *
   *     $client = new Client([
   *         'base_uri'        => 'http://www.foo.com/1.0/',
   *         'timeout'         => 0,
   *         'allow_redirects' => false,
   *         'proxy'           => '192.168.16.1:10'
   *     ]);
   *
   * Client configuration settings include the following options:
   *
   * - handler: (callable) Function that transfers HTTP requests over the
   *   wire. The function is called with a Psr7\Http\Message\RequestInterface
   *   and array of transfer options, and must return a
   *   GuzzleHttp\Promise\PromiseInterface that is fulfilled with a
   *   Psr7\Http\Message\ResponseInterface on success. "handler" is a
   *   constructor only option that cannot be overridden in per/request
   *   options. If no handler is provided, a default handler will be created
   *   that enables all of the request options below by attaching all of the
   *   default middleware to the handler.
   * - base_uri: (string|UriInterface) Base URI of the client that is merged
   *   into relative URIs. Can be a string or instance of UriInterface.
   * - **: any request option
   *
   * @param array $config Client configuration settings.
   *
   * @see \GuzzleHttp\RequestOptions for a list of available request options.
