[huangtianhua]

1. create a stack with a nova server, the template as bellow:
*******************
resources:
 hth_server:
    type: OS::Nova::Server
    properties:
      image: {get_param: image}
      networks: [{uuid: 27f21725-4f84-447b-8a93-581580e132dd}}]
      flavor: 1
      name: {get_param: name}
***************************

2. the stack in CREATE_COMPLETE, and the server in active, and has an ip in network(27f21725-4f84-447b-8a93-581580e132dd)
3. update the stack: update the server to another network(36182127-d01e-488a-97af-463f1b5ef4fe), and using 'uuid' instead of 'network'
*******************
resources:
 hth_server:
    type: OS::Nova::Server
    properties:
      image: {get_param: image}
      networks: [{uuid: 36182127-d01e-488a-97af-463f1b5ef4fe}}]
      flavor: 1
      name: {get_param: name}
***************************

    Fix ResourceGroup validate when there are removal_policies

    We can't call child_template() from a validate in ResourceGroup

    We are persisting for a number of reasons:
