CRT Transfer Client to support streaming

### Describe the feature

In the V2 CLI documentation it states that in streaming scenarios the preferred_transfer_client will revert to default if crt is selected. Why is this the case and can we please have crt in the streaming case.

### Use Case

I have a customer asking for streaming support for PUTting objects to S3, but they want maximum performance and are limited at the moment using the existing command line tooling.

### Proposed Solution

Enable streaming use cases in the CLI that make use of CRT under the hood. CRT supports streaming, its a matter of enabling it.
