[0405ysj]

When this PR is merged, I expect users are able to use podcvd with following steps. Of course, most steps will be reduced with further contributions.

# UID/GID setup
sudo apt install podman -y
sudo usermod --add-subuids 600000-665535 --add-subgids 600000-665535 $(whoami)
podman system migrate

# Device permission setup
sudo setfacl -m u:$(whoami):rw /dev/kvm
sudo setfacl -m u:$(whoami):rw /dev/vhost-net
sudo setfacl -m u:$(whoami):rw /dev/vhost-vsock

# Build cuttlefish-podcvd debian package
cd ${PATH_TO_ANDROID_CUTTLEFISH}
docker build \
  --file "tools/buildutils/cw/Containerfile" \
  --tag "android-cuttlefish-build:latest" \
  .
docker run -v=$PWD:/mnt/build -w /mnt/build android-cuttlefish-build:latest frontend

# Critical user journey
sudo apt install -y ./cuttlefish-podcvd_*.deb
podcvd create --vhost_user_vsock=true --report_anonymous_usage_stats=y
