Add LocalStack (V1) container for zio 2.0

[grouzen]

This PR adds LocalStack container V1 for ZIO 2.0 only.

I also opened another PR in testcontainers-scala to allow dockerImageName overrides, and not only tag: testcontainers/testcontainers-scala#246. I think it would be good to wait until the testcontainers-scala PR is merged and make changes to this one accordingly.
Update: testcontainers-scala is bumped up to 0.40.15

I'm going to add documentation if this approach is fine.

This shows an example of overriding endpoints of LocalStack services.

That's the way testcontainers-scala provides these dependencies. I decided to stick to their approach.

I believe this is the latest version of zio-aws that uses ZIO 2.0.9. Usage of more recent versions causes NoClassDefFoundError. It should be updated after the ZIO version is bumped up.

Fixing the compilation error...

Hi, I have implemented something similar and opted to directly integrate it with zio-aws.
It does work and allows for parallel testing, which plays great with zio-test by default parallelism.

The interesting/useful thing is on how to get the actual AWS config as it turns out that you don't need to have service-specific endpoints, therefore you don't need to pass the Service enum value in the TestContainer API to get an endpoint and instead get a layer to be reused by all services, which is great if you have code using multiple services. You just provide the layer 😃

Even though may not want to depend on zio-aws, it would be great to expose the endpoint directly to simplify the usage, as most users will think they need to pass the Service enum to get the endpoint.

  val awsConfig: ZLayer[Any, Throwable, CommonAwsConfig] = ZLayer.scoped {
    for {
      localstack <- makeContainer(LocalStackV2Container.Def(
        tag = "2.0.2",
        // Services are loaded lazily in latest localstack so need to be specific.
        services = Service.values()
      ))
      hostIpAddress <- ZIO.attempt(InetAddress.getByName(localstack.host).getHostAddress)
      // All services are found in the same port in latest locastack, so no service-specific mapping needed
      port <- ZIO.attempt(localstack.mappedPort(4566))
      uri <- ZIO.attempt(new URI(s"http://${hostIpAddress}:${port}"))
    } yield CommonAwsConfig(
      region = Some(Region.EU_WEST_1),
      endpointOverride = Some(uri),
      credentialsProvider = localstack.staticCredentialsProvider,
      commonClientConfig = None
    )
  }

Hope it helps !

TLDR: Updates to Localstack make the API container API from testcontainers outdated, as you don't need to either specify which services you need, nor get service-specific ports. So the org.testcontainers.containers.localstack.LocalStackContainer.Service enum becomes pretty much useless.

Dropping the withServices and endpointOverride methods (as there are very limited reasons to not use the latest localstack version) will help users avoid a legacy API which leads to quite complicated usage, especially when using zio layers.
