     * Factory method to create a new Amazon Data Pipeline client using an array of configuration options:
     *
     * Credential options (`key`, `secret`, and optional `token` OR `credentials` is required)
     *
     * - key: AWS Access Key ID
     * - secret: AWS secret access key
     * - credentials: You can optionally provide a custom `Aws\Common\Credentials\CredentialsInterface` object
     * - token: Custom AWS security token to use with request authentication
     * - token.ttd: UNIX timestamp for when the custom credentials expire
     * - credentials.cache: Used to cache credentials when using providers that require HTTP requests. Set the true
     *   to use the default APC cache or provide a `Guzzle\Cache\CacheAdapterInterface` object.
     * - credentials.cache.key: Optional custom cache key to use with the credentials
     * - credentials.client: Pass this option to specify a custom `Guzzle\Http\ClientInterface` to use if your
     *   credentials require a HTTP request (e.g. RefreshableInstanceProfileCredentials)
     *
     * Region and Endpoint options (a `region` and optional `scheme` OR a `base_url` is required)
     *
     * - region: Region name (e.g. 'us-east-1', 'us-west-1', 'us-west-2', 'eu-west-1', etc...)
     * - scheme: URI Scheme of the base URL (e.g. 'https', 'http').
     * - base_url: Instead of using a `region` and `scheme`, you can specify a custom base URL for the client
     *
     * Generic client options
     *
     * - ssl.certificate_authority: Set to true to use the bundled CA cert (default), system to use the certificate
     *   bundled with your system, or pass the full path to an SSL certificate bundle. This option should be used when
     *   you encounter curl error code 60.
     * - curl.options: Array of cURL options to apply to every request.
     *   See http://www.php.net/manual/en/function.curl-setopt.php for a list of available options
     * - signature: You can optionally provide a custom signature implementation used to sign requests
     * - signature.service: Set to explicitly override the service name used in signatures
     * - signature.region:  Set to explicitly override the region name used in signatures
     * - client.backoff.logger: `Guzzle\Log\LogAdapterInterface` object used to log backoff retries. Use
     *   'debug' to emit PHP warnings when a retry is issued.
     * - client.backoff.logger.template: Optional template to use for exponential backoff log messages. See
     *   `Guzzle\Plugin\Backoff\BackoffLogger` for formatting information.
     *
