Re: New experimental feature: import application from Docker Compose

> PR https://github.com/openshift/origin/pull/7690 introduces a new

> The following features should be enabled:
> 
> * Each service in the compose file is converted to its own deployment config
>   * Containers that share volumes or the local network are colocated
> in the same pod
>   * Environment values are copied
> * Each deployment config gets a Kubernetes service created that serves
> the ports exposed by each compose service
> * For each "build" directive, the local source is set up as a build
> config from OpenShift if we can find an upstream remote
>   * If there is no remote, you should have a binary build setup.
>   * Local context directories should be respected when you have a
> multi-service compose
> * Resource constraints defined on each compose service are applied as
> OpenShift requests or limits on the pods.

Since docker-compose recently changed its schema [1], does this PR support both?
