    /**
     * Factory method to create a default client using an array of configuration options.
     *
     * The following array keys and values are available 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. Please note that not all services accept temporary credentials. See http://docs.aws.amazon.com/STS/latest/UsingSTS/UsingTokens.html
     * - token.ttd: UNIX timestamp for when the custom credentials expire
     * - 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 (Some services do not require a region while others do. Check the service specific user guide documentation for details):
     *
     * - 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') used when base_url is not supplied
     * - base_url: Allows you to specify a custom endpoint instead of building one from the region and scheme
     *
     * Generic client options:
     *
     * - signature: Overrides the signature used by the client. Clients will always choose an appropriate default signature. However, it can be useful to override this with a custom setting. This can be set to "v4", "v3https", "v2" or an instance of Aws\Common\Signature\SignatureInterface.
     * - ssl.certificate_authority: Set to true to use the bundled CA cert or pass the full path to an SSL certificate bundle
     * - curl.options: Associative of CURLOPT_* cURL options to add to each request
     * - 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.
     *
     * @param array|Collection $config Client configuration data
     *
     * @return self
