feature(devcontainer): add llama cli/api

[mkellerman]

I have found a different api that may offer more flexibility when it comes to api support and speed.

Both should be evaluated and see which one is best for your use case.

Thanks! I think I will go with extendible compose files: one for the mocked API, one for llama-cli, and one for llama-cpp-python. I'm just waiting for my PR to be included so I don't have to add extra Dockerfiles:
abetlen/llama-cpp-python#73

llama-cpp-python has a Docker image now: https://github.com/abetlen/llama-cpp-python/pkgs/container/llama-cpp-python
