**Describe the bug** <!-- A clear and concise description of what the bug is. --> Attempting to perform a list request using a prefix containing a space results in a signature error. ``` <Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided. Check your key and signing method ... ``` This is because IAM requires always percent encoding all spaces - https://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html > Percent-encode all other characters with %XY, where X and Y are hexadecimal characters (0-9 and uppercase A-F). For example, the space character must be encoded as %20 (not using '+', as some encoding schemes do) This is normally the case as we explicitly percent encode paths - https://github.com/apache/arrow-rs/blob/master/object_store/src/aws/client.rs#L471 However, we delegate to reqwest for percent encoding of query parameters, and it uses `+` instead of `%20`. **To Reproduce** <!-- Steps to reproduce the behavior: --> **Expected behavior** <!-- A clear and concise description of what you expected to happen. --> **Additional context** <!-- Add any other context about the problem here. --> -- This is an automated message from the Apache Git Service.
