New compose spec breaks volume labels

[teutat3s]

I'm not sure if this is the right place to report this - I'd like to share the following findings though.

Docker Compose v1.27+ introduced a new unified compose spec that seems to cause some breakage with the triton docker API

@teutat3s Can you provide an example log from sdc-docker showing the differences in the requests it's receiving from docker-compose?
