Port range

[blop]

Hello,

It seems there is no way to configure a range of ports in docker-compose.yml.

It's supported by docker with something like -p 1234-1236:1234-1236/tcp
https://docs.docker.com/reference/run/#expose-incoming-ports

I could not make it work with docker-compose 1.4.0.

Thanks.

It was added in #1827, it will be in the 1.5.0 release
