Why add user home in devcontainer

@ShenFeng312 im guessing the idea is for accessing any user configs, but my feeling is that its probably not necessary, at least as the default.

relatedly i wonder what the utiltity of the CAPs above are - they essentially allow the container to root the host (altho i guess mitigated by running as non-root).

im perhaps not the best person to review as i dont use vscode myself - but would be happy to review any cleanups to this setup - as far as i can

@phlax Can you tell me what tools you use for development? I'm not particularly keen on using VSCode either. However, it seems like the official documentation mainly covers VSCode-related topics. I'm doing development on Ubuntu desktop. Also, the files generated by Envoy compilation are too large. The envoy-build volume is occupying around 20GB of disk space (possibly more; I deleted the previous container due to issues).

mostly emacs, but im not going to recommend doing that unless you are already an emacs user

... the files generated by Envoy compilation are too large.

i think that is pretty unavoidable, especially if you want a debug build

The envoy-build volume is occupying around 20GB of disk space ...

the default/recommended way of running is with ./ci/run_envoy_docker.sh this mounts a temp volume from fs (default is /tmp/envoy-docker-build) - i export ENVOY_DOCKER_BUILD_DIR=/home/phlax/bazel_cache before using this way to ensure i reuse cache and dont fill my /tmp directory
