2472: Add support for container_name in docker-compose file

[reggiemcdonald]

Closes: #2472

This PR adds support for container_name in the docker-compose file by pulling the container names out in ParsedDockerComposeFile and adding some additional logic in DockerComposeContainer

This is my first time contributing to the repo, so any feedback is welcomed.

I'm not really sure about this failing CI. Any suggestions? I just rebased with master, and it wasnt failing before the rebase

@reggiemcdonald I just triggered a re-run, there was some issue with downloading Gradle stuff

[reggiemcdonald]

@bsideup thanks!

@rnorth @bsideup @kiview having this feature is a blocking issue for me is there a plan to merge this change in?

Thanks for the PR @reggiemcdonald, but unfortunately we have to close it. Mainly, there are 2 reasons why we don't want to add support for container_name to DockerComposeContainer:

1. It requires us to further parse the Docker Compose file and its format has been slightly volatile in the past. So we generally want to avoid further semantically parsing the Docker Compose file, independent from the actual container_name key.
2. Using container_name would break existing DockerComposeContainer features, like scaling.
3. As the Testcontainers library, we want to avoid the usage of fixed things, such as ports, names, etc., since those introduce the anti-pattern of integrated tests that can fail depending on the state of the environment in which they are running.
