    S3-backed FileSystem implementation

If neither access_key nor secret_key are provided, and role_arn is also not
    provided, then attempts to initialize from AWS environment variables,
    otherwise both access_key and secret_key must be provided.

If role_arn is provided instead of access_key and secret_key, temporary
    credentials will be fetched by issuing a request to STS to assume the
    specified role.

Note: S3 buckets are special and the operations available on them may be
    limited or more expensive than desired.

Parameters
    ----------
    access_key : str, default None
        AWS Access Key ID. Pass None to use the standard AWS environment
        variables and/or configuration file.
    secret_key : str, default None
        AWS Secret Access key. Pass None to use the standard AWS environment
        variables and/or configuration file.
    session_token : str, default None
        AWS Session Token.  An optional session token, required if access_key
        and secret_key are temporary credentials from STS.
    anonymous : boolean, default False
        Whether to connect anonymously if access_key and secret_key are None.
        If true, will not attempt to look up credentials using standard AWS
        configuration methods.
    role_arn : str, default None
        AWS Role ARN.  If provided instead of access_key and secret_key,
        temporary credentials will be fetched by assuming this role.
    session_name : str, default None
        An optional identifier for the assumed role session.
    external_id : str, default None
        An optional unique identifier that might be required when you assume
        a role in another account.
    load_frequency : int, default 900
        The frequency (in seconds) with which temporary credentials from an
        assumed role session will be refreshed.
    region : str, default 'us-east-1'
        AWS region to connect to.
    scheme : str, default 'https'
        S3 connection transport scheme.
    endpoint_override : str, default None
        Override region with a connect string such as "localhost:9000"
    background_writes : boolean, default True
        Whether file writes will be issued in the background, without
        blocking.
    default_metadata : mapping or KeyValueMetadata, default None
        Default metadata for open_output_stream.  This will be ignored if
        non-empty metadata is passed to open_output_stream.
    proxy_options : dict or str, default None
        If a proxy is used, provide the options here. Supported options are:
        'scheme' (str: 'http' or 'https'; required), 'host' (str; required),
        'port' (int; required), 'username' (str; optional),
        'password' (str; optional).
        A proxy URI (str) can also be provided, in which case these options
        will be derived from the provided URI.
        The following are equivalent::

S3FileSystem(proxy_options='http://username:password@localhost:8020')
            S3FileSystem(proxy_options={'scheme': 'http', 'host': 'localhost',
                                        'port': 8020, 'username': 'username',
