Read COMPOSE_FILE from env and use it if it is set. Default is still
docker/local/docker-compose.yaml.
BREAKING CHANGE: Removed docker subcommand. Added deprecation notice to
compose subcommand.
Removed `completion` command in favor of compile time completion
generation. This tool will only be build from source for the foreseeable
future so this makes sense for now.
Exec is new command scoped under compose. It allows sending commands
directly into appserver container. I will make this
customizable/controllable in the future.
Made initial command scopes
d -> docker related commands
dc -> docker compose related commands
dj -> django related commands
pg -> postgres related commands
