  * 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
  *     - 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').
  *     - service: Specify the name of the service
  *     - base_url: Instead of using a `region` and `scheme`, you can specify a custom base URL for the client
  *     - endpoint_provider: Optional `Aws\Common\Region\EndpointProviderInterface` used to provide region endpoints
  * - Signature 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
  * - Exponential backoff options
  *     - 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.
  * - Generic client options
  *     - ssl.cert: Set to true to use the bundled CA cert or pass the full path to an SSL certificate bundle. This
  *           option should be used when you encounter curl error code 60.
  *     - curl.CURLOPT_VERBOSE: Set to true to output curl debug information during transfers
  *     - curl.*: Prefix any available cURL option with `curl.` to add cURL options to each request.
