Murali Reddy resolved CLOUDSTACK-7191.
--------------------------------------

    Resolution: Fixed

For the networks with VR as the only provider, restarting the network will not result in the clean up of the rules even if restartNetwork is called with cleanup=true option. VR should get destroyed immediately followed by recreating the VR followed by reprogramming the rules.

>
> RestartNetwork is implemented with below logical steps
>    
>    - clean up network rules on the provider (implemented by shutdownNetworkResources)
>   - shutdown the providers for the network
>  - implement all providers for the network
> - reprogram the rules
> step #1 is unnecessary in case the provider is appliance based like virtual router. so at present even for the VR significant amount of time is consumed to clean up the rules. This step is unnecessary as appliance will get destroyed any ways in next step.
> During upgrades in an environments with large number of networks with VR as the only provider, it will take significant time.
> This bug should ensure cleanup of rules is done only if required.
