### Background AWS provides a mechanism for using temporary credentials to access AWS resources. When accessing AWS resources with a set of temporary credentials,[ users must provide a session token](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_use-resources.html) in addition to the usual access key id and secret access key. This PR adds support for providing a session token when initializing an S3FileSystem. ### Changes #### C++ - updated `S3Options.FromAccessKey` and `S3Options.ConfigureAccessKey` to accept an optional `session_token` argument (defaulting to empty string, in accordance with the convention of [Aws::Auth::AWSCredentials](https://sdk.amazonaws.com/cpp/api/0.12.9/d4/d27/class_aws_1_1_auth_1_1_a_w_s_credentials.html) as implemented in the AWS C++ SDK.) - added `S3Options.GetSessionToken` method ##### Python - updated cdef `CS3Options` to reflect updates to C++ library - added optional `session_token` argument to `S3FileSystem.__init__`. ### Testing - updated `test_s3_options` python unittest to include a mock session_token when initializing S3FileSystem. - successfully ran ctest suite and pytest suite with `--enable-s3` option. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
