Remove usages of deprecated LocalStack code features in AWS replicator

Ninguém assumiu esta issue ainda.

Currently, the AWS Replicator extension is using some parts of the LocalStack codebase which is deprecated and about to be removed:
- `localstack.utils.server.http2_server.run_server` which is based on `Quart` (which has been superseded by the underlying `hypercorn` quite some time ago).
- `localstack.aws.api.HttpRequest` which should be replaced with `localstack.http.Request`.

These usages are currently blocking the following PRs in `localstack/localstack`:
- https://github.com/localstack/localstack/pull/9754
- https://github.com/localstack/localstack/pull/9757

It would be best to refactor the AWS Replicator Extension such that it spawns the Auth Proxy a new `Gateway` (and migrate the logic to a implement a LocalStack handlerchain handler).

Comece localizando os usos, pelo AWS Replicator, de localstack.utils.server.http2_server.run_server e localstack.aws.api.HttpRequest e, em seguida, revise os PRs vinculados do localstack para entender o contexto de compatibilidade. Considera-se concluído quando esses usos obsoletos forem removidos e o Auth Proxy for migrado para um Gateway e um LocalStack handlerchain handler.
