Remove usages of deprecated LocalStack code features in AWS replicator

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• localstack.utils.server.http2_server.run_server which is based on Quart (which has been superseded by the underlying hypercorn quite some time ago).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).

Inizia individuando gli utilizzi da parte di AWS Replicator di localstack.utils.server.http2_server.run_server e localstack.aws.api.HttpRequest, quindi esamina le PR di localstack collegati per il contesto di compatibilità. Il lavoro è completato quando questi utilizzi deprecati sono stati rimossi e Auth Proxy è stato migrato verso un Gateway e un LocalStack handlerchain handler.
