As of Go 1.16, the same functionality is now provided by package io or
package os, and those implementations should be preferred in new code.
So replacing all usage of ioutil pkg with io & os.

When using the "classic" (non-BuildKit) builder, ensure that
services are iterated in dependency order for a build so that
it's possible to guarantee the presence of a base image that's
been added as a dependency with `depends_on`. This is a very
common pattern when using base images with Compose.
A fix for BuildKit is blocked currently until we can rely on a
newer version of the engine (see docker/compose#9324)[^1].

Within the Docker API/engine, networks have unique IDs, and the
name is a friendly label/alias, which notably does NOT have any
guarantees around uniqueness (see moby/moby#18864 [^1]).
During day-to-day interactive/CLI Compose usage, this is rarely
an issue, as Compose itself isn't creating networks concurrently
across goroutines. However, if multiple Compose instances are
executed simultaneously (e.g. as part of a test suite that runs
in parallel), this can easily occur.
When it does happen, it's very confusing for users and resolving
it via the `docker` CLI is not straightforward either [^2].
There's two primary changes here:
* Pass `CheckDuplicates: true` to the Docker API when creating
networks to reduce the likelihood of Compose creating duplicates
in the first place
* On `down`, list networks using a name filter and then remove
them all by ID, as the Docker API will return an error if the
name alias is used and maps to more than one network
Hopefully, this provides a better UX, since the issue should be
less likely to occur, and if it does, it can now be resolved via
standard Compose workflow commands.

In v1, links were sent alongside the rest of the container create request, as part of `HostConfig`. In v2, links are usually set on the connect container to network request that happens after the create. However, this only happens if the service has one or more networks defined for it. If the services are configured to use the default bridge network, this request is not made and so links are never configured.

`NetworkInspect` will match a network ID by prefix. While rare,
it's possible that users might use a network name that is also
a valid network ID prefix for a pre-existing Docker network.
(In the reported case, the network was named `db`, for example.)
Fixes#9496.
