Migrate to DockerCompose V2

[balint-backmaker]

Motivation

• Docker Compose v2 offers more features that we can make use of and create a better developer experience.
• Docker Compose v1 will no longer be receiving updates after June 2023 so we should deprecate the usage of it

Notable features

• docker compose ps --format json can help us shortcut the effort on many useful things
• Update Docker Compose call when launching a Docker Compose command #226 is trivial after this and fairly safe to "prefer the plugin over the standalone"
• Compose should use compose_file_name=[] or None by default #259 may have been fixed in v2 but any fixes might be better implemented for v2
• Add a wait_for_healthcheck method to DockerCompose #241 is more trivial to implement once we have the json format available to us
• Make DockerCompose.get_service_info public #239 is also trivial as well as giving us a much richer set of data, including the easy shortcut to get the container ID and allow testcontainers to start/stop these containers

The challenges

• dual support of v1 and v2:
  • legacy support means tougher feature parity and more testing needed for something that is in fact deprecated
  • I'd like to drop it, but this means compose contains a breaking change
  • so what is the next major release for testcontainers-python ? 🙂
• docker compose v2 is not a python package (it's written in golang and I'm not sure I'm up for making a binding for this)
  • so need to agree on a sensible way to check this on instantiation of a DockerCompose object.
  • Not hard, just needs some reviews and is a breaking change

Final thoughts

I'm happy to pick this up, in fact I have a local copy with a bunch of goodies, just need some community support in how to introduce this change.

Also since this is likely a breaking change for the compose plugin, your thoughts on how to version this would be very welcome @tillahoffmann 🙏

This would be a really nice feature now that Docker compose v1 is EOL 🙏

here is how testcontainers-java does it
