Looks like the latest `github.com/docker/docker/registry.ResolveAuthConfig` expect
`github.com/docker/docker/api/types.AuthConfig` rather than
`github.com/docker/cli/cli/config/types.AuthConfig`. The two types are
identical but live in different packages.
Here, we embed `registry.ResolveAuthConfig` from upstream repo, but with
the signature we need.
Using the API as provided from the `mounts` package imposes validation
on the `src:dest` which shouldn't be performed at this time. To workaround
that lift the internal code from that library required to only perform
the split.
Support Docker `volumes` field in Windows. Previously, volumes parser
assumed some Unix-ism (e.g. didn't expect `:` in mount paths).
Here, we use the Docker parser to identify host and container paths.
Docker parsers use different validation logic from our previous unix
implementation: Docker parser accepts single path as a volume entry
(parsing it as a container path with auto-created volume) and enforces
additional checks (e.g. validity of mode). Thereforce, I opted to use
Docker parser only for Windows, and keep Nomad's linux parser to
preserve current behavior.
