We had Command and Args together with Entrypoint in Kompose object.
This doesn't make much sense, as Entrypoint and Command are same thing.
I've removed Entrypoint from Kompose object in favor of Command to keep

Entrypoint from docker-compose.yml is now saved to Command and Command
is saved to Args (http://kubernetes.io/docs/user-guide/containers/).
docker-compose.yml | Kompose object
-------------------|---------------
Entrypoint | Command
Command | Args
Sorts objects in Transform function, this should
make sure that Services are first everywhere as
long as we keep order in the slice that Transform returns.
