Add devcontainer for ACA-Py

[usingtechnology]

Addressing an issue where it is difficult to get set up to debug and begin coding by adding a devcontainer.

See Issue #2251 - this is only one small part of developer documentation. I wanted this out for feedback while we identify other areas of concern.

@amanji please check this out. @dbluhm, is there anyone on your team that regularly use Dev Containers?

[amanji]

So far so good, I was able to load the devcontainer in VSCode without any issues.

These are great! couple small comments
I started from scratch, didn't even have the dev container extension installed and can get things going with the instructions and container config here

I would add a note of what you can't do with a dev container -- notably running the various Docker-based tools in the repo (e.g. run_docker in the scripts folder, the run_demo in the demo/ folder. The devcontainer isn't setup to do docker-in-docker, so those can't be used. Not sure if they should be able to be used, so not a big issue, but should be mentioned since we lean heavily on those tools.

Looks great and after the first build is pretty fast!

Something that might be worth trying. Evidently, docker-in-docker is possible with devcontainers, as per this: https://github.com/devcontainers/features/tree/main/src/docker-in-docker. It might be interesting to see if with that added to the devcontainer config if the ACA-Py demos can be run.

Yes, I took a quick look at docker-in-docker, but didn't explore it fully (or try to implement it). I could spend more time on it if we want.

[swcurran]

How about for now, we just add a note about it in the readme, and an issue with a “help wanted” sign.

[dbluhm]

I don't have anyone on my team actively using devcontainers right now but I think this would be a great addition. I agree with Stephen on getting this merged sooner than later and plan on making further enhancements in the future.

added docker-in-docker and updated the devcontainer readme to show how to run the demos within the container.

For the devContainer, I'd recommend using bullseye rather than buster to keeps things consistent with the published images.

Thanks for that... updated

Tested out with running the demo and worked nicely. A couple of notes we can add, but overall looks good. Great work!
