EC2 IMDS Client about aws-sdk-kotlin HOT 1 CLOSED

I'm not entirely sure what this means, but as the only ticket we have for IMDS I'll put my recent findings here...

IMDS is a local "service" which yields credentials and other host information via an unmodeled and unstructured service IMDS. See these SEPs for additional info:
1. /seps/accepted/shared/imds-client.md
2./seps/accepted/shared/imds-credentials.md

AWS SDKs have sometimes bundled clients so that in cases where programs using a given AWS SDK are running on an EC2 host, those credientials and other information can be retrieved without adding another dependency, however there is nothing in common between generated AWS service clients and a IMDS client [1].

As CRT has implemented IMDS client internally, it does not make sense to build a pure Kotlin version unless there is some serious fault with the CRT provided client. Additionally, I believe a case could be made to ship this client as a discrete dependency as this functionality is only usable when running on EC2 hosts.

1: The Go V2 SDK's hand-written IMDS client reuses some existing middleware from it's SDK for retries but otherwise does not integrate with the service clients. Comments from the Go team regarding their implementation:

 if you're curious, here is the code for the IMDS client, https://github.com/aws/aws-sdk-go-v2/tree/main/feature/ec2/imds
[api_client.go](https://github.com/aws/aws-sdk-go-v2/blob/main/feature/ec2/imds/api_client.go)  and [api_op_GetMetadata.go](https://github.com/aws/aws-sdk-go-v2/blob/main/feature/ec2/imds/api_op_GetMetadata.go) are probably the most interesting, The middleware stuff is all based on [requiest_middleware.go](https://github.com/aws/aws-sdk-go-v2/blob/main/feature/ec2/imds/request_middleware.go)
