    # @overload initialize(options)
    #   @param [Hash] options
    #   @option options [required, Aws::CredentialProvider] :credentials
    #     Your AWS credentials. This can be an instance of any one of the
    #     following classes:
    #
    #     * `Aws::Credentials` - Used for configuring static, non-refreshing
    #       credentials.
    #
    #     * `Aws::InstanceProfileCredentials` - Used for loading credentials
    #       from an EC2 IMDS on an EC2 instance.
    #
    #     * `Aws::SharedCredentials` - Used for loading credentials from a
    #       shared file, such as `~/.aws/config`.
    #
    #     * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #     When `:credentials` are not configured directly, the following
    #     locations will be searched for credentials:
    #
    #     * `Aws.config[:credentials]`
    #     * The `:access_key_id`, `:secret_access_key`, and `:session_token` options.
    #     * ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    #     * `~/.aws/credentials`
    #     * `~/.aws/config`
    #     * EC2 IMDS instance profile - When used by default, the timeouts are
    #       very aggressive. Construct and pass an instance of
    #       `Aws::InstanceProfileCredentails` to enable retries and extended
    #       timeouts.
    #
    #   @option options [required, String] :region
    #     The AWS region to connect to.  The configured `:region` is
    #     used to determine the service `:endpoint`. When not passed,
    #     a default `:region` is search for in the following locations:
    #
    #     * `Aws.config[:region]`
    #     * `ENV['AWS_REGION']`
    #     * `ENV['AMAZON_REGION']`

    #     Required for publishing client metrics. The port that the client side monitoring
    #     agent is running on, where client metrics will be published via UDP.

    #     to default service endpoint when available.
    #
    #   @option options [String] :endpoint

    #
    #   @option options [Integer] :endpoint_cache_max_entries (1000)

    #   @option options [String] :profile ("default")
    #     Used when loading credentials from the shared credentials file
    #     at HOME/.aws/credentials.  When not specified, 'default' is used.
    #

    #
    #   @option options [Symbol] :retry_jitter (:none)

    #
    #   @option options [Integer] :retry_limit (3)
    #     The maximum number of times to retry failed requests.  Only
    #     ~ 500 level server errors and certain ~ 400 level client errors
    #     are retried.  Generally, these are throttling errors, data
    #     checksum errors, networking errors, timeout errors and auth
    #     errors from expired credentials.
    #
    #   @option options [Integer] :retry_max_delay (0)
    #     The maximum number of seconds to delay between retries (0 for no limit) used by the default backoff function.

    #
    #   @option options [String] :session_token
    #
    #   @option options [Boolean] :stub_responses (false)
    #     Causes the client to return stubbed responses. By default
    #     fake responses are generated and returned. You can specify
    #     the response data to return or errors to raise by calling
    #     {ClientStubs#stub_responses}. See {ClientStubs} for more information.
    #
    #     ** Please note ** When response stubbing is enabled, no HTTP
    #     requests are made, and retries are disabled.
    #
    #   @option options [Boolean] :validate_params (true)

    #
    #   @option options [Float] :http_continue_timeout (1) The number of
    #     seconds to wait for a 100-continue response before sending the
    #     request body.  This option has no effect unless the request has
    #     "Expect" header set to "100-continue".  Defaults to `nil` which
    #     disables this behaviour.  This value can safely be set per
    #     request on the session yeidled by {#session_for}.

    #     will be used if available.
    #
    #   @option options [String] :ssl_ca_directory Full path of the
    #     directory that contains the unbundled SSL certificate
    #     authority files for verifying peer certificates.  If you do
