By default, `compose up` attaches to all services (i.e. shows log output from every associated container). If a service is specified, e.g. `compose up foo`, then only `foo`'s logs are tailed. The `--attach-dependencies` flag can also be used, so that if `foo` depended upon `bar`, then `bar`'s logs would also be followed. It's also possible to use `--no-attach` to filter out one or more services explicitly, e.g. `compose up --no-attach=noisy` would launch all services, including `noisy`, and would show log output from every service _except_ `noisy`. Lastly, it's possible to use `up --attach` to explicitly restrict to a subset of services (or their dependencies). How these flags interact with each other is also worth thinking through. There were a few different connected issues here, but the primary issue was that running `compose up foo` was always attaching dependencies regardless of `--attach-dependencies`. The filtering logic here has been updated so that it behaves predictably both when launching all services (`compose up`) or a subset (`compose up foo`) as well as various flag combinations on top of those. Notably, this required making some changes to how it watches containers. The logic here between attaching for logs and monitoring for lifecycle changes is tightly coupled, so some changes were needed to ensure that the full set of services being `up`'d are _watched_ and the subset that should have logs shown are _attached_. (This does mean faking the attach with an event but not actually doing it.) While handling that, I adjusted the context lifetimes here, which improves error handling that gets shown to the user and should help avoid potential leaks by getting rid of a `context.Background()`.

Description
Builds, (re)creates, starts, and attaches to containers for a service.
Unless they are already running, this command also starts any linked services.
The docker compose up command aggregates the output of each container (like docker compose logs --follow does).
One can optionally select a subset of services to attach to using --attach flag, or exclude some services using
--no-attach to prevent output to be flooded by some verbose services.
When the command exits, all containers are stopped. Running docker compose up --detach starts the containers in the
background and leaves them running.
If there are existing containers for a service, and the service’s configuration or image was changed after the
container’s creation, docker compose up picks up the changes by stopping and recreating the containers
(preserving mounted volumes). To prevent Compose from picking up changes, use the --no-recreate flag.
If you want to force Compose to stop and recreate all containers, use the --force-recreate flag.
If the process encounters an error, the exit code for this command is 1.
If the process is interrupted using SIGINT (ctrl + C) or SIGTERM, the containers are stopped, and the exit code is 0.
