@amimimor can you please help review this PR?

Regarding this issue and associated pull request, @yaron2 and I are currently discussing the proposed implementation, which depends on the AWS Go SDK version 2 library directly and indirectly. AFAIK, the Components ecosystem for this project has not yet migrated to using version 2 of the AWS Go SDK.

We need to evaluate whether now is the appropriate time to introduce a dependency on v2, or if we should consider alternative implementations that are compatible with the v1 SDK that is currently used across components.

[amimimor]

LGTM.
Note, for future reference that this is the first time the project uses AWS Go SDK v2 module (while the rest of the project uses v1)

@famarting please check the failing checks, specifically the build check and the Kafka pubsub certification test
