Read default postgres compose service name and default django compose
service name from env variables.
AHAB_POSTGRES_CONTAINER - defaults to `appserver`
AHAB_DJANGO_CONATINER - defaults to `postgresdb`
Default values are there for 100% backwards compatibility.
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.
Allow for starting just some of the containers. This will be needed for
implementing postgres::import where we'll need to stop all containers
and then only start postgres container.
Implemented basic wanted functionality for docker compose subcommands.
We currently assume that docker-compose.yaml file is located in
local/docker/ folder.
Made initial command scopes
d -> docker related commands
dc -> docker compose related commands
dj -> django related commands
pg -> postgres related commands
