[CRT] - Allow setting max bandwidth limit for S3 transfers

### Describe the bug

I'm trying to limit S3 bandwidth for CRT runtime described in https://aws.amazon.com/blogs/storage/improving-amazon-s3-throughput-for-the-aws-cli-and-boto3-with-the-aws-common-runtime/

I used the following command (from the article)

```
aws configure set s3.target_bandwidth 50MB/s
```

despite that I see much higher bandwidth (limited by hard disk drive actually)

aws cli version: `aws-cli/2.17.61 Python/3.12.6 Windows/2022Server exec-env/EC2 exe/AMD64`

in classic (non crt) mode bandwidth limiting works like a charm.

### Regression Issue

limiting bandwidth in crt mode

### Current Behavior

not limiting (even configured as per article)

### Reproduction Steps

install aws cli
aws configure set s3.preferred_transfer_client crt
aws configure set s3.target_bandwidth 50MB/s

copy files to s3, verify speed
