    Revert the destroy execution order

    Restores back the order of .destroy execution so that
    child objects get destroyed first and Environment get
    destroyed last.

    Both orders have their cons and pros. With
    the current order Environment and thus Heat stack
    are delete first so if the app sends a command to
    murano-agent in its destroy method it will never
    receive an answer since the VM of the agent was
    already terminated. This broke Kubernetes and might
    broke other apps as well. However the downside is that
    apps are going to perform uninstall of the software
    on VM that is going to be terminated anyway which
    takes time. But until we implement a controllable
    resource deallocation this looks like a safer approach.
