Async support for WebIdentityTokenCredentialsProvider

[tms0]

Describe the feature

Add support for WebIdentityTokenCredentialsProvider to use an async client

Use Case

Same use case than in this previous issue : #1881

If I understand correctly, the new STSWebIdentityTokenCredentialsProvider didn't add the ability to use an async client. So we still need to add a sync http client on the classpath to use the WebIdentityTokenCredentialsProvider.

Proposed Solution

@tms0 the STS client is only used to make the assumeRoleWithWebIdentity call. Is there any particular reason you need to use the async client? Do you explicitly remove the sync clients from the classpath?

Hi @debora-ito,

I use the Quarkus extension (https://github.com/quarkiverse/quarkus-amazon-services/tree/main) which explicitly exclude all the http clients to let us include only those needed.

But currently, I have to include both an async client (because I want to do non-blocking programming) and a sync client to use the WebIdentityTokenCredentialsProvider.

As a good practice, and particulary in a Quarkus / GraalVM world, I want to include as few dependencies as possible.
