Validate role on cluster platforms

[cdelgehier]

Hello,

For roles like galera or zookeeper, I changed the create.yml to generate me N container (instead of just one)

extract of molecule.yml

…
platforms:
  - name: ${PROJECT_ID:-default}-galera-u1804
    image: "geerlingguy/docker-ubuntu1804-ansible:latest"
    pre_build_image: true
    volumes:
      - /sys/fs/cgroup:/sys/fs/cgroup:ro
    privileged: true  # required for accessing to systemd
    groups:
      - galera_u18
    count: 3

  - name: ${PROJECT_ID:-default}-galera-c7
    image: "geerlingguy/docker-centos7-ansible:latest"
    pre_build_image: true
    volumes:
      - /sys/fs/cgroup:/sys/fs/cgroup:ro
    privileged: true
    groups:
      - galera_c7
    count: 3

But when provisioning the inventory is not correct. The doculentation says : Molecule automatically generates the inventory based on the hosts defined under Platforms.

How can it know my other containers?
