We just called `manage` inside docker instead of
`exec appserver python manage.py`. Now we make assumption that django
app is running in docker-compose in service named `appserver`.
While fixing this bug we also refactored for `shell`, `makemigrations`
and `migrate` to all call `manage` under the hood to avoid repeating code.
Implemented basic wanted functionality for postgres subcommands. We
currently assume that postgres is running in docker-compose project in a
service named "postgresdb". This could be looked at and changed at some
point 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
