The docker-compose.original is there intentionally in order to show the difference between the original and modified docker-composes

ok, i can revert those back but then you have to keep track of version from this to the next release? IMO, it is too much burden for developer

So for example, the previous one would be renamed to something like docker-compose.2.x or something like that
