feat: add opentelemetry instrumentation

[scrocquesel]

Fix #1049

Adding the following dependency to a project will automatically include an interceptor with default AwsSdkTelemetry configuration in all generated clients that have opted into instrumentation. This is achieved by setting the configuration property quarkus.<extension>.telemetry.enabled to true.

<dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-opentelemetry</artifactId>
</dependency>
