Move SDK http client to CRT

Describe the solution you'd like
As the CRT http client is now available (https://aws.amazon.com/blogs/developer/announcing-availability-of-the-aws-crt-http-client-in-the-aws-sdk-for-java-2-x/), we could use it in the modules we use the SDK (Parameters, Idempotency, SQS, CloudFormation) to reduce the cold start and latency.

Due to the scale, we should do this on one module first for review, and then go from there. Idempotency would be a good candidate.

@jeromevdl @msailes I can pick this up

I think this should be tagged v2. It's not really a breaking change as it's internal but it introduces a new library and quite a new way of doing things (asynchronous).
