    Adds support for several applications in single Pod

    Kubernetes doesn't allow to add containers to a Pod that
    is already deployed. With this change old pods will be deleted
    and either new pod created which will include new container
    or Replication Controller will be modified (before Pod delete
    so that updated Pods be created instead)

    Also now Pods are created only when replica number set to 0.
    Otherwise Pods created by ReplicationController alone.
