Custom DOCKER_EXTRA_ARGS

[blackliner]

Is there a way for users to provide custom, additional args to the docker run command?

export DOCKER_EXTRA_ARGS='--mount source=my-data-volume,target=/app/data'
# results in the following being called when launching a devcontainer
docker run <devcontainer_specific_stuff> --mount source=my-data-volume,target=/app/data <container_image> <commands>
