/**
* 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.
* - 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.
* - 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_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.
* - 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.
