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()`.

If we go to inspect a container that we got an event for and it
no longer exists on the server, handle clean up without erroring
out.

Also add e2e tests to ensure `compose up --wait` does not get stuck forever waiting for one-shot containers

Fixes#8747
When the event is a container destroy, calling ContainerInspect returns
an error, because the container no longer exists. This causes both
`docker-compose up` and `docker-compose logs -f` to exit when removing a
stopped container.
This container has already emitted its die event, and has already been
cleaned up. I believe all that needs doing in this case is to early-out.
