    /**
     * The client constructor accepts the following options:
     *
     * - api_provider: (callable) An optional PHP callable that accepts a
     *   type, service, and version argument, and returns an array of
     *   corresponding configuration data. The type value can be one of api,
     *   waiter, or paginator.
     * - credentials:
     *   (Aws\Credentials\CredentialsInterface|array|bool|callable) Specifies
     *   the credentials used to sign requests. Provide an
     *   Aws\Credentials\CredentialsInterface object, an associative array of
     *   "key", "secret", and an optional "token" key, `false` to use null
     *   credentials, or a callable credentials provider used to create
     *   credentials or return null. See Aws\Credentials\CredentialProvider for
     *   a list of built-in credentials providers. If no credentials are
     *   provided, the SDK will attempt to load them from the environment.
     * - csm:
     *   (Aws\ClientSideMonitoring\ConfigurationInterface|array|callable) Specifies
     *   the credentials used to sign requests. Provide an
     *   Aws\ClientSideMonitoring\ConfigurationInterface object, a callable
     *   configuration provider used to create client-side monitoring configuration,
     *   `false` to disable csm, or an associative array with the following keys:
     *   enabled: (bool) Set to true to enable client-side monitoring, defaults
     *   to false; host: (string) the host location to send monitoring events to,
     *   defaults to 127.0.0.1; port: (int) The port used for the host connection,
     *   defaults to 31000; client_id: (string) An identifier for this project
     * - debug: (bool|array) Set to true to display debug information when
     *   sending requests. Alternatively, you can provide an associative array
     *   with the following keys: logfn: (callable) Function that is invoked
     *   with log messages; stream_size: (int) When the size of a stream is
     *   greater than this number, the stream data will not be logged (set to
     *   "0" to not log any stream data); scrub_auth: (bool) Set to false to
     *   disable the scrubbing of auth data from the logged messages; http:
     *   (bool) Set to false to disable the "debug" feature of lower level HTTP
     *   adapters (e.g., verbose curl output).
     * - stats: (bool|array) Set to true to gather transfer statistics on
     *   requests sent. Alternatively, you can provide an associative array with
     *   the following keys: retries: (bool) Set to false to disable reporting
     *   on retries attempted; http: (bool) Set to true to enable collecting
     *   statistics from lower level HTTP adapters (e.g., values returned in
     *   GuzzleHttp\TransferStats). HTTP handlers must support an
     *   `http_stats_receiver` option for this to have an effect; timer: (bool)
     *   Set to true to enable a command timer that reports the total wall clock
     *   time spent on an operation in seconds.
     * - disable_host_prefix_injection: (bool) Set to true to disable host prefix
     *   injection logic for services that use it. This disables the entire
     *   prefix injection, including the portions supplied by user-defined
     *   parameters. Setting this flag will have no effect on services that do
     *   not use host prefix injection.
     * - endpoint: (string) The full URI of the webservice. This is only
     *   required when connecting to a custom endpoint (e.g., a local version
     *   of S3).
     * - endpoint_discovery: (Aws\EndpointDiscovery\ConfigurationInterface,
     *   Aws\CacheInterface, array, callable) Settings for endpoint discovery.
     *   Provide an instance of Aws\EndpointDiscovery\ConfigurationInterface,
     *   an instance Aws\CacheInterface, a callable that provides a promise for
     *   a Configuration object, or an associative array with the following
     *   keys: enabled: (bool) Set to true to enable endpoint discovery,
     *   defaults to false; cache_limit: (int) The maximum number of keys in the
     *   endpoints cache, defaults to 1000.
     * - endpoint_provider: (callable) An optional PHP callable that
     *   accepts a hash of options including a "service" and "region" key and
     *   returns NULL or a hash of endpoint data, of which the "endpoint" key
     *   is required. See Aws\Endpoint\EndpointProvider for a list of built-in
     *   providers.
     * - handler: (callable) A handler that accepts a command object,
     *   request object and returns a promise that is fulfilled with an
     *   Aws\ResultInterface object or rejected with an
     *   Aws\Exception\AwsException. A handler does not accept a next handler
     *   as it is terminal and expected to fulfill a command. If no handler is
     *   provided, a default Guzzle handler will be utilized.
     * - http: (array, default=array(0)) Set to an array of SDK request
     *   options to apply to each request (e.g., proxy, verify, etc.).
     * - http_handler: (callable) An HTTP handler is a function that
     *   accepts a PSR-7 request object and returns a promise that is fulfilled
     *   with a PSR-7 response object or rejected with an array of exception
     *   data. NOTE: This option supersedes any provided "handler" option.
     * - idempotency_auto_fill: (bool|callable) Set to false to disable SDK to
     *   populate parameters that enabled 'idempotencyToken' trait with a random
     *   UUID v4 value on your behalf. Using default value 'true' still allows
     *   parameter value to be overwritten when provided. Note: auto-fill only
     *   works when cryptographically secure random bytes generator functions
     *   (random_bytes, openssl_random_pseudo_bytes or mcrypt_create_iv) can be
     *   found. You may also provide a callable source of random bytes.
     * - profile: (string) Allows you to specify which profile to use when
     *   credentials are created from the AWS credentials file in your HOME
     *   directory. This setting overrides the AWS_PROFILE environment
     *   variable. Note: Specifying "profile" will cause the "credentials" key
     *   to be ignored.
     * - region: (string, required) Region to connect to. See
     *   http://docs.aws.amazon.com/general/latest/gr/rande.html for a list of
     *   available regions.
     * - retries: (int, default=int(3)) Configures the maximum number of
     *   allowed retries for a client (pass 0 to disable retries).
     * - scheme: (string, default=string(5) "https") URI scheme to use when
     *   connecting connect. The SDK will utilize "https" endpoints (i.e.,
     *   utilize SSL/TLS connections) by default. You can attempt to connect to
     *   a service over an unencrypted "http" endpoint by setting ``scheme`` to
     *   "http".
     * - signature_provider: (callable) A callable that accepts a signature
     *   version name (e.g., "v4"), a service name, and region, and
     *   returns a SignatureInterface object or null. This provider is used to
     *   create signers utilized by the client. See
     *   Aws\Signature\SignatureProvider for a list of built-in providers
     * - signature_version: (string) A string representing a custom
     *   signature version to use with a service (e.g., v4). Note that
     *   per/operation signature version MAY override this requested signature
     *   version.
     * - validate: (bool, default=bool(true)) Set to false to disable
     *   client-side parameter validation.
     * - version: (string, required) The version of the webservice to
     *   utilize (e.g., 2006-03-01).
     *
     * @param array $args Client configuration arguments.
     *
     * @throws \InvalidArgumentException if any required options are missing or
     *                                   the service is not supported.
